What is the correct way to clean a food thermometer?

Like any kitchen utensil, food thermometers should be washed with hot, soapy water. Most thermometers should not be immersed in water. Wash them carefully by hand.

What is the proper internal temperature for cooking meat and poultry?

We recommend: cooking hamburgers made with ground beef, veal and lamb at 160 ° F (71.1 ° C); all poultry whole or in pieces must reach a minimum adequate internal temperature of 165 ° F (73.9 ° C); c Ocine all roasts, steaks , and chops, raw meat of beef, pork, lamb and calf, until a minimum internal temperature of 145 ˚F (62.8 ° C), the measure to a food thermometer before removing meat the heat source. For safety and quality, allow a standing time of at least three minutes before mincing and consuming the meat. For reasons of personal preference, consumers may choose to cook meats to a higher temperature.

At what temperature should I cook the pork?

The USDA recommends cooking ground pork, in kibble or in mixes, such as that used for meatloafs, until it reaches an internal temperature of 160 ° F (71.1 ° C), when measured with a food thermometer. Cooks organ meats (such as heart, liver, pancreas, tongue, and intestines) to 160 ˚F (71.1 ˚C).Cook all raw pork steaks, chops and roasts to a minimum internal temperature of 145 ˚F (62.8 ˚C), as measured with a food thermometer, before removing the meat from the heat source. For safety and quality, allow a standing time of at least three minutes before mincing and consuming the meat. For reasons of personal preference, consumers may choose to cook meats to a higher temperature. For more information on temperatures and approximate cooking times.

What is an oven thermometer?

Unlike a food thermometer that indicates the temperature of meat or poultry, an oven thermometer measures the temperature of the air in the oven. It can be left in the oven to verify that it is heating up to the desired temperatures. These bimetallic spiral thermometers can measure temperatures from 100 degrees to 600ºF (37.78 to 315.56ºC).

What types of kitchen thermometers are available?

Much information on the use of food thermometers is available on the Food Safety and Inspection Service (FSIS) website. For information (including illustrations) on various types of thermometers and their use.

Can I use a human thermometer to measure the temperatures of meat and poultry?

Thermometers used to measure human body temperature do not indicate temperatures high enough for cooking. They are not manufactured to withstand temperatures above 106 ˚F (41.1 ºC). Therefore, never use a medical thermometer for cooking.

What is the temperature at which bacteria grow the fastest?

Most bacteria grow faster at temperatures between 40 and 140 ° F (4.4 ° C and 60 ° C), doubling in number in as little as 20 minutes. The temperature range is often called the "Danger Zone". To learn more about the "Danger Zone".

What is a bimetallic spiral thermometer?

Bimetallic coil thermometers contain a coil in the probe made of two different metals that are joined together. The two metals have different rates of expansion. The spiral, which is connected to the temperature gauge, expands when heated. This food thermometer senses the temperature from its tip and goes up the tube 2 to 2 1/2 inches (5 to 6.3 cm). The resulting temperature is the average of the temperatures across the detection area.

What is a corded oven thermometer?

A corded oven food thermometer allows the cook to check the temperature of the food in the oven without having to open the oven door. A base unit with a digital display is attached to a thermistor type food thermometer probe by means of a long metal cord. The probe is inserted into the food and the cord is extended from the oven to the base unit. The thermometer is programmed for the desired temperature and beeps when it is reached. They can also be used to check food that is cooked on a stove. Cannot calibrate oven cord thermometers.

What is an instant read thermometer?

Instant-read bimetallic spiral thermometers measure the temperature of a food in about 15 to 20 seconds. They are not designed to stay in the food when it is cooked in the oven. Use near the end of the calculated cook time to measure final cook temperatures. For an accurate temperature measurement, insert the probe the full length of the sensing area (usually 2 to 3 inches). If the temperature of a thin food (hamburger or boneless chicken breast) is to be measured, insert the probe through the side of the food so that the entire sensing area is positioned through the center of the food. Some models can be calibrated. Consult the manufacturer's instructions. For more information on thermometers and the different types please see the following information sheet.

Can oven safe, bimetallic, spiral thermometers be used in an oven?

Yes. This type of thermometer was designed to stay in a food when it is cooked in an oven and is generally used for large foods such as a roast or turkey (turkey). Because the temperature sensing coil in the tube is 2 to 2 1/2 inches long and relatively thick, it is not suitable for measuring the temperature of any food that is less than 3 inches.

What is a fork thermometer?

It is a combination of a cooking fork and a food thermometer. It is a temperature sensitive device embedded in one of the tines of the fork. Temperature is indicated on a digital display or by indicator lights on the handle within 2 to 10 seconds. Especially useful for grilling, the fork thermometer will accurately measure the internal temperature of even the thinnest foods, but it is not designed to remain in the food while it cooks. Check the temperature near the end of the estimated cook time. The thermometer cannot be calibrated.

Thermometers

 Thermometers

Good temperature control is critical in many aspects and disciplines of the kitchen. Depending on what we are preparing, it will be important to know at what temperature an oven is, or the oil or water in which we are going to cook. The temperature also allows us to know what is happening in areas that we cannot see: is my roast beef raw inside? The interior temperature of the piece will tell us. To this end, cookware manufacturers are developing increasingly precise, easy-to-use and versatile appliances. Here is a short list that is not intended to be complete.

- Thermometers and Instant-Read Thermometers Product

Let's start with the cold: yes, the fridge and freezer are undoubtedly the most important and critical elements of our kitchen. Having them well regulated is important and in this we are not only concerned with the quality of those we conserve but also our own health. The refrigerator should be between 2 and 4ºC. The freezer should be at least -18ºC. There may be several reasons why a refrigerator does not reach the desired temperature, and although it is not the object of this article, I give you some possible causes: poorly adjusted thermostat, lack of gas in the compressor, refrigerator too full, refrigerator with insufficient ventilation on the back ... And the way to know for sure that our fridge is cooling as expected, is to use a thermometer. Most models are suitable for both the fridge and freezer.

Oven temperature

Oven temperature : depending on how sophisticated your oven is, it may have its own temperature indicator. Many cooks, despite having ovens with this functionality, are not quite trustworthy and prefer to also have a good quality thermometer that is placed inside the oven (on a tray or hung from a rack) so that it can be read from the window without opening the door. This is essential since the simple act of opening an oven door can momentarily lower its interior temperature drastically. These thermometers are special for oven and most measure maximum temperatures of 300 or 350ºC.

Liquid temperature

Liquid temperature: the European Union has just banned the sale of mercury thermometers. But in addition, liquid column thermometers (mercury or other) are fragile and relatively inaccurate. There are also the so-called bimetallic foil thermometers (those that look like a clock with a needle that moves a spring). These are not very precise either and in my opinion they have a very specific use that we will see later. With what we have left digital thermometers, which are the ones I recommend. They are affordable, read almost instantly, and are versatile. They measure quite wide temperature ranges and serve both to measure the temperature of a liquid and to see the internal temperature of a food (and that is why they are shaped like a needle).

Meat thermometers

Meat thermometers : if we want to monitor the internal temperature of a piece of meat or a chicken that we are roasting in the oven without having to open the door each time, we will need a meat thermometer. It is left punctured in the piece making sure that the end of the thermometer needle reaches approximately the center of the piece. And we do it in such a way that we can read the thermometer from the oven window. Thus, without having to open the door, we will know at all times what temperature is in the heart of our roast. Many of these thermometers also add a "cutlet" that reminds us of what temperature beef, pork and chicken should be to be undercooked, medium or well cooked.

This meat thermometer allows us to make sure that our roast is always ready, but it forces us to always be near the oven door “monitoring” the temperature. There is another model of thermometers (which we also have in the Cocinista store) that solves this problem in a very witty way. It is a thermometer whose probe is connected to the central unit by a heat resistant cable. We will puncture the probe in the food and close the oven door, which will catch the probe cable but will not break it. In the central unit we will see the temperature of the part, but what is more important, we can program an alarm that will warn us as soon as the center of it reaches the desired temperature. Unless we go very far from the kitchen, we will never eat roasts again! Say that this thermometer also serves to measure temperatures of liquids. The cable with the probe can be disconnected and we have the central unit which is a clock and a timer. Can you tell that I love this product?

Finally, mention a thermometer that we will see especially in professional kitchens: I am referring to the infrared thermometer. It is similar to a "gun" that we will have to aim at the object or liquid whose temperature we want to know, appearing instantly on a screen. They are undoubtedly very "cool" but I do not know if their use in a domestic kitchen is justified. In addition, to measure the temperature accurately, you have to make manual adjustments that can be complex.

What is an infrared thermometer and what is it for?

An infrared thermometer, also called a non-contact remote thermometer or pyrometer , is a device for measuring the body temperature of humans by emitting a beam of black-body light. As it does not have to be in direct contact with the skin , it is ideal for detecting fever in people with contagious diseases. This has been evident in its usefulness to combat COVID-19.

This non-contact temperature measurement device is often referred to as a laser thermometer. However, it is a mistake . This is because it uses that technology to correctly direct that beam of blackbody light onto the skin, but not to perform the measurement.

Are Infrared Thermometers Safe?

Infrared digital thermometers are totally safe . The reason is that they do not produce infrared radiation , but only measure it. Therefore, they can be used in babies, children, adults and the elderly without problems. Of course, they are not as reliable as traditional digital thermometers, although almost.

Additionally, by not requiring contact between the device and the user, infrared thermometers reduce the risk of disease transmission . This makes them even more secure.

Why should you have an infrared thermometer and not a traditional thermometer?

• Infrared digital thermometers offer all these advantages over any type of conventional manual or digital thermometer:
• They make faster readings . The best infrared thermometers offer results in less than 5 seconds.
• They make it easy to take the temperature since it can be done directly from the forehead. In fact, infrared baby thermometers are especially helpful. Young children don't make it easy to use a glass contact thermometer when they are sick.
• They allow a reading history and a practical temperature monitoring . This is unique to memory pyrometers which generally allow user profiles to be created and up to 25 records of each can be saved.
• They are multifunction devices . They are also useful as infrared thermometers for food, for room temperature, etc.
• They are totally safe since they do not emit infrared radiation or involve contact with the patient, which reduces the risk of contagion of infectious diseases.
• In most cases, these are infrared thermometers with an easy-to-read LCD display .

How do infrared thermometers work?

All objects and living beings that are at a temperature above absolute zero (-273º C) emit infrared radiation . Human beings are not an exception, although that type of light cannot be perceived with our eyes. However, medical infrared thermometers can.

Infrared clinical thermometers detect that infrared radiation that we emit through the skin and direct it towards a lens. To do this, they usually use a beam of laser light that is harmless to humans; once there, depending on its intensity and wavelength, they transform it into an electrical signal . Depending on its characteristics, it is converted to a value in degrees Celsius or Fahrenheit that we can quickly understand.

Parts of an infrared thermometer

• Infrared energy sensor .
• Beam of laser light to focus that radiation towards the lenses.
• Optical system for capturing IR light.
• Unit for converting IR radiation to electrical signal .
• Unit of conversion of electrical signal to degrees Celsius or Fahrenheit.
• LCD screen to display the results.
• Ergonomic handle with trigger to perform the measurement.

Types of infrared thermometers

We can distinguish the following:

• Gun-type infrared thermometers - These are the easiest to use due to their ergonomic design and non-slip handle. They are located between 2 and 5 cm from the skin and take the measurement automatically. They are the recommended infrared thermometers for the home.
• Frontal infrared thermometers : they receive this name since they are specifically designed to capture body temperature from the forehead.
• Infrared body thermometers : they can measure anywhere on the body, not just the forehead.
• Infrared thermometers for objects and liquids : They are not infrared thermometers for humans, but for food, metals and materials of all kinds. They are also known as digital multimeters.

How do you use an infrared thermometer?

Very easy:

• Turn on the infrared thermometer by pressing the ON / OFF button .
• The display will light up. Wait for dial 00.0º C .
• Place the tip 2 to 5 cm from the skin . There are also infrared ear thermometers, which are also called tempean, whose end must be inserted into the ear.
• Press the button located on the trigger.
• Wait for the audible warning to indicate that the measurement has finished.
• The measurement results will appear on the screen.

How do you know if an infrared thermometer is accurate?

Depending on the model and its quality, the margin of error of infrared thermometers for people is in a temperature range of +/- 0,1-0,3º C . This figure is considerably lower than that of mercury or gallium thermometers, which are strongly influenced by ambient temperature.

To ensure the accuracy of the DMM, you can take two consecutive measurements . The results should be the same in both cases. If they are not, you probably need to calibrate it. This, without specific devices and inside the home, can be a bit difficult. In case the manufacturers do not include in the instruction manual information about how to perform the calibration of infrared thermometers , you should do the following:

• Put water in a saucepan to heat .
• Wait for it to boil completely . This will indicate that the water has reached 100ºC .
• Keep the fire going and take a temperature measurement over the water with your infrared thermometer.
• If it does not read 100ºC, adjust the temperature manually to calibrate it.

How do you read an infrared thermometer?

It has no mystery as the temperature is displayed on an LCD screen by large digits . Typically, the information is displayed in degrees Celsius or centigrade. However, some models from abroad measure the temperature in degrees Fahrenheit. Going from Fahrenheit to Celsius is very easy. It is based on the fact that 0º C is 32º F and that, from there, for every 1º C you have to add 1.8º F. Thus, for example, 36º C, which is the normal temperature of a person, is equivalent at 96.8º F.

What is the normal temperature of a person?

The normal temperature in babies, children, adolescents, adults and the elderly is the same . However, it can vary from one subject to another by a few tenths. It can even change depending on the area of ​​the body in which it is measured. Therefore, it is considered that:

• Between 36.1º C (97º F) and 37.2º C (99º F): normal temperature .
• Between 37.3º C (99.14º F) and 38.1º C (100.58º F): low-grade fever or mild fever .
• Between 38.2º C (100.76º F) and 39º C (102.2º F): moderate fever .
• 39º C (102.2º F) or more: high fever .

What to do in case of high temperature?

It depends. If you have a low-grade fever or mild fever (37.3ºC-38.1ºC), it is best to take an antipyretic drug that does not require a prescription, such as paracetamol or ibuprofen. Most likely it will be down in a few hours. As soon as you detect it, you should make an appointment for your family doctor. On the other hand, if you have a moderate fever (38.2º C-39º C), we advise you to take the antipyretic and go to an outpatient emergency service or medicine that cannot be delayed . In case you do not have any nearby, it is advisable to go to a hospital. Remember to go with a mask as it may be due to an infectious and contagious process. Finally, if you detect a high fever (+ 39º C) in yourself or someone in your family, put yourself or put them in the hands of an emergency doctor immediately. In the event of delusions or loss of consciousness, it is best to call the Emergency Telephone (112) or the Emergency Service of your autonomous community. In most of them it is 061.

How do you know if you have a fever without a thermometer?

It is not possible . Traditional remedies such as, for example, placing the hand on the forehead of the patient are not effective, although they can act as indicators. The same happens with these symptoms :

• Rosy cheeks and ears.
• Feeling hot or cold for no apparent reason.
• Sudden sweating without just cause.
• Muscle pain, especially in the lower back and legs.
• Moderate or severe headache.
• Glassy eyes.

However, these symptoms, neither together nor separately , can be used to know that you have a fever for sure. You can only be certain that this is the case using a thermometer.

Where do you sell infrared thermometers?

You already know everything you need to buy an infrared thermometer. However, you still have to know in which commercial and physical establishments you can find them. These are the best:

• Pharmacies : some already have them for sale. Ask in those near your home to purchase infrared thermometers for children and adults and receive advice from the pharmacist.
• Amazon : without a doubt, the ideal marketplace to find the best infrared thermometers on the market. It has a wide selection of models available at greatly reduced prices. In addition, it offers excellent shipping and return conditions, especially for Amazon Prime subscribers.
• El Corte Inglés : another good alternative if you also want to see, touch and test the infrared thermometer before purchasing it. They are found in the parapharmacy section of your supermarkets and your online store.

What kind of maintenance does an infrared thermometer have?

• Whether it is a cheap infrared thermometer or one of the best on the market, if you want it to last for a long time in perfect condition, you should take the following into account:
• Store it in a place away from direct sunlight and moisture . This will prevent your battery and electronic components from deteriorating prematurely. Use, if possible, the packaging provided by the manufacturer.
• Disinfect the thermometer after each use with a dry cloth and a little rubbing alcohol. It is true that it does not require physical contact, but it is always better to be safe. In addition, your hands may have touched the patient and have virus particles or infectious microorganisms.
• Perform the calibration of the infrared thermometer periodically following the instructions described in the section “ How to know if an infrared thermometer is accurate? "

The best baby thermometers to measure your temperature at any time

 The best baby thermometers to measure your temperature at any time

An essential element in every home is a thermometer and, even more so, if there is a baby in the family

Fever is the increase in body temperature in response to illness . The frequency with which it is had and the degrees of temperature are key information when diagnosing a pediatrician. Therefore, we cannot trust only to put the hand in the forehead. You need to know the exact temperature and, for this, it is best to have a thermometer on hand.

- The best baby thermometers to measure your temperature at any time and Instant-Read Thermometers Product

Mercury thermometers were used in the past but, for a few years, the European Union banned these devices for domestic use due to their danger. Mercury thermometers are made of glass and can therefore easily break and release the highly toxic mercury.

If what we want is to take our baby's temperature , it is best to opt for any of the models that exist today. There are many types of thermometers, from digital to gallium, through infrared, pacifier, ear or plastic strips. These are, in our opinion, the best baby thermometers on the market .

Best, Our Pick : HYLOGY Baby Thermometer

63% of Amazon user reviews give it 5 out of 5 stars. Many users emphasize that it can be used both to measure the temperature on the forehead and in the ear. For Saioa the important thing is that "I have taken the temperature while the child slept and he has not even found out." Javier stressed that " it is very easy to use ( even grandma uses to measure the temperature of my son)", while for Mariana the most important thing is that " it is a very accurate thermometer."

Frida, for her part, explains that it is “ quite accurate . The ambient temperature matches and the reading in front is correct too ”.

It is a very accurate thermometer with a range of ± 0.3 ˚C, as it has an exceptional microchip and a high sensitivity sensor. It allows taking the temperature of the forehead, but also that of the ear or that of other objects (milk, food, bath water or the environment). It is an ear thermometer suitable for both the family and the hospital, after powerful clinical trials conducted by medical experts and pediatricians. With CE / FDA / ROHS certificate, it is recommended by the health sector. Hygienic and non-toxic , it is safer than traditional mercury thermometer. Has 20 memory readings to track, fever alarmand color distinction (green temperature within normal and red with fever) and silent mode. The feedback is colored LED and has an automatic shutdown to save energy.

Alternative: DrKea Baby Thermometer

The Drkea Thermometer is a professional and accurate dual-mode fever thermometer for babies, children and adults. It has a 4 out of 5 star rating . Joaquín shows his opinion like this: "It's perfect. It was what I was looking for and it has good value for money."

This infrared thermometer can be placed on the forehead or ear without disturbing the baby. It has a simple configuration . It goes from measuring temperature from ear to forehead to room with a single button and has a clear icon to show you the selected function. Easily switch between Celsius and Fahrenheit by holding down the "MEM" button for 3 seconds.

How to choose a baby thermometer and what to consider before buying one?

When it comes to getting a baby thermometer it is important to take into account several factors that can help us tell by one or the other model.

• Precision. The most important thing about a thermometer is that it measures the temperature correctly. It's no use being very intuitive if the data is wrong.
• Applications. We have to know if we only want the thermometer to measure fever or if we want to know the temperature of food, the water in the bathtub or the environment. Depending on what we need, we must choose one option or another.
• Complexity. The more it facilitates us to measure the baby's temperature, the better. Children get nervous, take it off, cry. If the handling is simple and fast, it will help us to spend these moments with the children in a better way. In addition, if we leave them in the care of other people, it is better that they have at their disposal a device that is easy to use and does not complicate their lives.
• Energy. It is applied in digital thermometers. At the very least, a quality battery should hesitate at least a year.
• Memory. Thermometers that record the results are very useful in children and in illnesses like the flu.
• Price . It depends a lot on the above factors, especially the brand and type. The simplest digital can be around 8 or 10 euros. The 4 in 1, with alarm, silent mode, memory, etc. They can be around 20.

It is also important to pay attention to the type of thermometer , since there are several models.

• Mercury : as we have commented, despite their precision, in the European Union they are prohibited due to their high toxicity both for people and for the environment.
• Gallium: to replace the previous one, another equally reliable material was sought. Gallium is like that, but the drawback is that you have to spend a lot of time with it under the armpit (4 minutes) or in the rectum (2 minutes).
• Digital : they have transducers and electronic circuits that convert temperature variations into digitized numbers. Their electrical resistance varies depending on the voltage obtained, and they can be set in Celsius or Fahrenheit scales. They have LCD screens and also have multiple functions that are very useful.
• Infrared: physical contact with the baby is not necessary, since they are placed about 5 centimeters from your forehead or ear. However, there may be some environmental variation. These are more used in children and the elderly than in adults, so as not to disturb them, for example, while they sleep.
• Pacifier: it is inserted into the baby's mouth. If the child does not use a pacifier, it may not work, because it will be difficult for him to hold it in his mouth and suck.
• By ear: they have a flexible probe to place in the ear canal. Some infrared is used for the forehead and ear, and you just have to wait for the temperature to show on the screen.
• Plastic strap : it is placed on the forehead or on the wrist as a bracelet, but it is not very reliable.

What is a thermometer?

A thermometer is a device used to measure temperature . Galileo Galilei is credited with the creation because he was the first to create the thermoscope (a device that showed changes in temperature).

What is it for and how is a thermometer used?

The main function of a thermometer is to measure temperature . The wide variety that exists is due to the different uses. From the best known, to measure human fever, to those used in industrial production and that must withstand very high temperatures. There are also those used to measure the environment, others for wine or cooking, etc.

Types of baby thermometers

There are some thermometers that are better adapted to the characteristics of a baby. They are not easy to convince and less when they are asleep. Therefore, for babies the most common are:

• Digital forehead thermometers : measured with infrared. Some need skin contact and some don't.
• Ear thermometers - Infrared is directed into the ear canal.
• Pacifier thermometer: Experts cannot agree on whether they are reliable or not.
• Plastic strip thermometers: they change color depending on the temperature, but they are not the most reliable either.
• Digital thermometers: the most common. They are used in both adults and babies. They are placed in the armpit, mouth or rectum and usually take around a minute.

When is a high fever considered?

Low-grade fever is between 37º and 37.5ºC. It is when it is said colloquially that " there are a few tenths ", and it indicates that something is not right. In adults there is usually a fever from 37.5ºC , but in babies and children from 38ºC.

What is the normal temperature for a 0-5 month old child?

The temperature of a person can vary from one to another and changes depending on the time of day it is taken. There are different factors that influence (the temperature of the environment, if you have eaten food, if you have exercised ...) But the normal temperature ranges are from 35.8 to 37.3 ºC . Above, it is considered a low-grade fever. For babies the ranges are exactly the same as for adults.

How do you know if a baby has a fever without a thermometer?

There are symptoms that give very reliable clues to know if the baby has a fever, although at that moment you do not have a thermometer at hand.

• Skin temperature : temperature is felt to the touch. If you put your hand on your forehead you can feel if it is hot. Do not touch the hands or feet because they could be cold, even with a high temperature.
• Flushed skin: 'blushes' sometimes appear on the cheeks. In darker skin it is less noticeable.
• Bright eyes : glassy eyes, as if to cry, is another characteristic.
• Thirsty: due to heat and dehydration.
• Decay: produced by the intrinsic discomfort of fever
• Pains: sometimes it produces headaches or a feeling of heaviness.
• Sensation of cold or heat : it can cause chills or, conversely, a feeling of great heat.
• Respiratory rate: sometimes the respiratory rate also increases.

What is the highest temperature for a baby?

Most doctors and the American Academy of Pediatrics (AAP) agree that normal body temperature for a healthy baby is between 97 and 100.3 degrees Fahrenheit ( 36 and 38 degrees Celsius). If your baby's rectal temperature is above 38 degrees C (100.4 F), he has a fever.

It will depend on the age and condition of the baby to proceed in one way or another. With babies under three months you should see a doctor if you have a fever . You could have an infection, inflammation, or a serious illness. Teething does not usually cause a fever over 38.2 ºC If it is older than 3 months, the important thing is to observe its behavior. If you are in good spirits and drink fluids, it is not necessary to see a doctor. On the contrary, after 24 hours the fever continues or increases, take it to a professional.

The AAP recommends calling the doctor if your child is 3 to 6 months old and has a temperature of 38.3 degrees, or if he is older than 6 months and has a temperature of 39.4 degrees or higher.

How to make the fever go down fast?

Here are some helpful tips to lower a fever:

• Avoid excess clothing: remove some clothing if it is very warm, to avoid more heat.
• Hydrate - Make sure you drink fluids so you don't get dehydrated.
• Regulate the environment: the temperature should not exceed 21 degrees.
• Warm Water Bath - Warm water helps disperse heat. It should not be too cold, since the temperature shock can harm the child.
• Water-damp cloths: refresh the neck and forehead with a cloth dampened with warm water, not cold.

What are the most recommended baby thermometers?

Some brands that we recommend for their value for money and for the opinion of users are Hylogy, SVMUU, Medisana, Drkate, Braun and Beurer . All of them can be found in pharmacies, in specialized baby stores, in department stores or in many online stores. With this quick buying guide, getting a baby thermometer will be easier: analyze your needs, evaluate all the options and buy the best cheap baby thermometer you need.

• -Sick with contagious conditions : infrared laser digital thermometer since it avoids direct contact.

It is also important to take into account the type of operation , which can be:
Infrared laser : it is a type of digital thermometer that does not require physical contact.
Classic : using thermistors that detect temperature according to variations in skin tension.

What is a digital thermometer and what is it for?

A digital thermometer is an electronic device used to measure body temperature and detect if a person has a fever . To do this, it has a system of integrated circuits that record the voltage variations produced in the skin, mouth or ear and transform them into a numerical value. This is converted to degrees Celsius or Fahrenheit and is displayed on a screen almost instantly.

The rise in temperature usually precedes fever or general malaise so having a thermometer handy is very useful

eye! A digital kitchen thermometer is not valid for measuring fever in people. Its degree of sensitivity is lower when having to operate with more extreme temperatures.

Digital or mercury thermometers?

Digital thermometers for detecting fever in adults, babies, and children are undoubtedly better than mercury thermometers . Let's see why:

• Greater precision : there is no more effective system than a digital body thermometer to detect fever. Mercury is a heavy metal that can be altered by environmental conditions and by contact with the user's fingers.
• Easier to Use - No need to shake digital thermometers before use. This is only necessary in the classic mercury thermometer to unify the mineral and expand according to the detected temperature.
• Faster : The best digital thermometers show the temperature in degrees centigrade in a few seconds Mercury ones can take up to 5 minutes to show a reliable measurement.
• Safer : Mercury is a very toxic element. If the thermometer is broken, released, and touched, inhaled, or eaten, it can lead to serious health problems and even death. This is especially concerning in the case of children. However, it is a risk that does not exist in digital thermometers for temperature measurement.

In Spain and in many other countries the sale of mercury thermometers is prohibited due to the toxicity of this heavy metal. However, there are people who still have them in their homes. The health authorities recommend its replacement as soon as possible. Of course, you should not confuse classic mercury thermometers with gallium thermometers . Both have a similar operating system, but the latter are not toxic.

How do digital thermometers work?

First, you must know what elements make up any digital thermometer:

• Thermistor : it is located at the tip of the thermometer. It is a device that, depending on the temperature of the area, varies its resistance to the passage of electricity.
• Integrated circuit : integrates the thermistor and is responsible for transmitting the information to the transducer.
• Transducer : collects the information from the thermistor and, using an analog-digital converter, transforms the voltage into a binary number.
• Display or digital screen : responsible for facilitating the reading of body temperature.

That said, operating a digital baby or adult thermometer is relatively straightforward. The thermistor of the integrated circuit detects small variations in voltage produced in the skin that modify the temperature. Depending on the value of this, the electric current has more or less difficulty to pass through it. That information collected by the thermistor is transmitted to the transducer as a voltage. This has an analog-digital converter that converts the voltage into a binary number. Then, using the information stored in your memory, you just have to convert those digits into degrees Celsius or Fahrenheit. Finally, the device screen shows the reading data.

What is the normal body temperature?

Body temperature varies depending on age, the activity you are doing, or the time of day . It can even vary between two subjects exposed to the same conditions. Therefore, all values between 36.1º C (97º F) and 37º C (98.6º F) are considered normal . Does this mean that if your body temperature drops below 36º C you have hypothermia and if it rises above 37º C you have a fever? Not necessarily . It will depend on your individual characteristics and many other external factors. Therefore, it is important that you take measurements when you are not sick to know what is the normal temperature in you and what is not.

How safe are digital thermometers?

Digital thermometers are 100% safe . This is because they work without glass that can break and without mercury or other metal that can be toxic. Its use does not pose any risk to children or adults.

Types of digital thermometers

We can distinguish different types of digital thermometers depending on where they should be used :

• Tympanic digital thermometer : or digital ear thermometer. Measure the temperature by inserting the tip of the thermistor into the ear and reaching the cavity of the eardrum. It is very reliable.
• Oral and armpit digital thermometer : it receives this name since, generally, it can be used to measure body temperature both in the mouth and in the armpit. It is the most used by adults, but also the least accurate.
• Rectal digital thermometer: it is a temperature meter whose thermistor must be inserted through the anus. It is the digital thermometer recommended for babies and the seriously ill. It offers extraordinary precision.

However, it is also possible to differentiate two types of thermometers depending on their mode of operation :

• Contact digital thermometer : should be placed in the armpit, rectum, mouth or ear to detect temperature. That is, it must remain in contact with the skin or enter a body cavity.
• Infrared digital thermometer : unlike the previous one, it works without body contact. It is also called a forehead thermometer since it can detect fever in babies, children and adults from the forehead. It is a very fast and ideal system when there is a risk of contagion of an infectious disease. In fact, it is the one used by health authorities during the COVID-19 pandemic.

How do you use a digital thermometer?

Very easy:

• Press the power button on the LCD digital thermometer.
• Wait for the numbering to reset .
• Place the thermometer in the area recommended by the manufacturer (armpit, ear, etc.).
• Wait for the acoustic signal to indicate the end of the measurement.
• The display will now indicate the temperature.

If it is a non-contact digital forehead thermometer, you just have to put it about 2-3 cm from the skin and wait for the screen to reflect the measurement.

How do you know if a digital thermometer works well?

These are some common problems in digital thermometers and their corresponding solutions:

• The screen does not turn on : the battery is probably dead. Put in a new digital thermometer battery (usually button-type) and try again. If it does not light, consult the warranty of the seller and / or the manufacturer.
• The display shows 'LO' : this occurs because the ambient temperature was too low prior to the measurement. Repeat it and it will be fine.
• Measurements give different results : no need to take two consecutive measurements. If you do, the second is most likely higher than the first. However, the correct one will be the first.

In what areas of the body can a digital thermometer be used?

It will depend on the type of digital thermometer. These are:

• Armpits : fever is considered above 37.2ºC . It is the recommended area for adults but not the most reliable. But which armpit do you put the digital thermometer in? Does not matter. The results are the same in both.
• Mouth : here it is determined that there is a fever from 37.3ºC . It is also not very accurate.
• Ear : a good option for children and contagious patients. There is a fever if the measurement rises above 37.5ºC .
• Straight : the most precise area, but the most uncomfortable. If the measurement exceeds 37.6 ° C , the subject has a fever.
• Front : 37º C is the reference value. Only a wireless infrared or laser thermometer works here. The others are not valid.

How do you calibrate a digital thermometer?

Even the best digital thermometers must be periodically calibrated to correctly detect high body temperature. Specifically, you should do it before the first use, after a fall or if you think the reading is incorrect. There are two effective methods to see if a mercury-free digital thermometer needs to be calibrated:
Fill a glass with crushed ice and add water to the brim. Stir and wait 3 minutes before inserting the thermometer. It should read 0º C (32º F).
Put a glass of water in a saucepan. Bring it to the boiling point and insert the thermometer. If it says 100º C (212º F), that's fine.

But what if you don't indicate the correct value? Typically, the digital thermometer has a button or a calibration wheel. Press or turn it until the display shows 0 or 100, depending on the system you choose. It is ready to use again.

How do you read a digital thermometer?

You just have to check the screen and read the temperature . You will be able to know if you have a fever by comparing the reading with the comments in the section "In which areas of the body can a digital thermometer be used?".

How to read a digital thermometer in Fahrenheit?

Generally, digital pharmacy thermometers allow readings in degrees Celsius and Fahrenheit . In Spain we usually use the former to make measurements, but not in other countries. Therefore, if your model comes from abroad, you may run into the problem that it only measures the temperature using degrees Fahrenheit. However, going from Fahrenheit to Celsius is very simple. 0º C to 32º F equal and 100º C to 212º F . You will have a fever if your measurement returns between 98.6º F (37º C) and 104º F (40º C) or higher .

How do you know if you have a fever without a digital thermometer?

It is impossible to know for sure . The usual thing is to put the hand on the forehead, but it is not an effective method since it influences the thermal sensation of the skin of the hand. In any case, there are symptoms and indicators that we may have a fever:

• Headache.
• Fatigue.
• General discomfort.
• Pain concentrated in the legs and lower back.
• Rosy cheeks

These are symptoms associated with fever, but neither individually nor as a whole do they necessarily imply that your body temperature has risen due to the activity of your immune system. Keep that in mind.

What to do if the temperature is above 37 degrees?

Many factors can trigger a fever and not all are necessarily serious. This guide can be helpful: - Between 37º C and 38º C : it is considered a mild fever. A simple antipyretic (paracetamol or aspirin, for example) without a prescription can help you lower it. Of course, you should make an appointment with your family doctor so that he can see you as soon as possible. Check the evolution of the fever every hour. - Between 38º C and 39º C : this temperature range is already considered high. Go to an outpatient clinic as soon as possible to be seen by your family doctor or the non-delayed service. - Between 39º C and 40º C or more : these are dangerous figures and indicate a serious infection. You should go to an outpatient or hospital emergency department immediately. Many people, when exceeding 39º C, experience delusions and loss of consciousness. In those cases, it is best to call the Emergency Telephone 112.

Maintenance and cleaning of digital thermometers

Digital thermometers are used on people who are usually sick. Therefore, it is vitally important to clean and disinfect them in this way after each use:

• With a cloth dampened in hot water and detergent , clean the tip and body of the thermometer.
• Dry it with a cloth cloth.
• Apply 70º alcohol and let it evaporate on its own.
• Put it back in its case and store it in a place away from the sun and humidity .

Only by performing these steps after each use will you avoid the accumulation and transmission of pathogenic microorganisms and viruses from one person to another inside the home. Knowing this and everything else that we have just told you, you will be sure when it comes to buying the best digital thermometer for you and your family .

BEST KITCHEN THERMOMETERS

 BEST KITCHEN THERMOMETERS

If you are a chef, you cannot miss a thermometer in your kitchen! With it you will get better results in your dishes, discover how it can help you, the different uses and types that exist.

To use a thermometer you do not have to be a professional chef, and the important thing is that knowing how to measure the temperature of food will give you better results in your dishes, achieving a more precise and tasty cooking because food thermometers are an extremely useful tool. and indispensable on many occasions.

- BEST KITCHEN THERMOMETERS and Instant-Read Thermometers Product

Controlling the temperature during cooking is an essential step in many recipes. Anyone who needs to temper chocolate, bake with sourdough, or make flawless caramel will know this.

There are many types of thermometers on the market and to use one, the first rule of thumb is to know what the standard temperatures are for cooking food, some examples are:

• Oil for frying is between 170 ° C and 180 ° C
• Fish or white meat at 62ºC
• Red meat not well done at 50ºC

BECAUSE YOU ARE INTERESTED IN A KITCHEN THERMOMETER
It is true that by tradition there are many people who continue to stick a knife or a toothpick when roasting, check the color or try to feel the temperature with their fingertips. There is nothing wrong with it, but the technique also evolves in the kitchen, and in the end the most reliable method to get an idea of ​​the degree of doneness is through a precise measurement thanks to a kitchen thermometer.

After all, the perfect oven does not exist and the temperature is never constant. Even in the most modern and expensive ovens, and those used by professionals. When indicating the temperature of our oven, it varies over time: the oven starts with a higher temperature than the one we have indicated and then lowers it to reach the required degrees. Later, the temperature goes down and up, generating multiple temperature fluctuations of around +/- 20 ° C during cooking. As if that were not enough, it must be borne in mind that there is no point in the oven that has the same temperature as another.

To minimize these fluctuations a tip is to heat the oven at least one hour before baking. The temperature will be more stable and the quality of the results will improve.

HOW TO BETTER KNOW THE TEMPERATURE OF OUR OVEN

If we want to have a control of the temperature at which our oven is, there are oven thermometers that measure the interior temperature during the cooking of dishes, not the temperature of the food we are cooking. They are made of stainless steel, with a hook to easily hang them over the container.

We can keep this thermometer in the oven but let's not forget to clean it from time to time because it gets dirty with the fat from food when we cook. Its temperature ranges between 50 ° C and 350 ° C.

Thermometers can also be useful to check that the temperatures of the fridge and freezer are adequate for the preservation of the most perishable foods such as meat and fish, especially if we have had a power failure and we want to know if the food has remained very cold or frozen or if you have to, unfortunately, throw everything away.

WHEN THE KITCHEN THERMOMETER IS VERY NECESSARY

We are already clear about how important it is to check the exact temperature of the oven or freezer when we are with meat or fish, but there are also many other preparations in which precise temperature control is essential, for example:

• To melt sugar and prepare syrups or candies
• Fried foods, it is important to control the temperature of the oil
• When we need to control the increase in temperature, in particular, for example when baking bread or cake that requires fermentation
• When we want to temper the chocolate
• In the preparation of yogurt
• To serve wine and beer at the right temperature

TYPES OF KITCHEN THERMOMETERS:

Thermometers are commonly divided into contact thermometers, which work by insertion, and infrared thermometers, which are those used in the professional field. For those who enjoy cooking, the former are more interesting and there are several types: for roasts (in the heart), probe, for frying, chocolate, caramel, fermenting doughs and also two very specific ones for yogurt and wine.

HEART TEMPERATURE THERMOMETER (OR ROAST THERMOMETER)

Its long metal probe allows us to reach the central point of the preparation and check the core temperature. Using it is as simple as inserting it into the piece of meat to quickly check the internal temperature, and then removing it.

We may find that some of these thermometers are designed to withstand oven heat, while others are not heat resistant, and should only be used for a quick check during cooking. The most classic are analog.

To ensure that we have made a good measurement, it is necessary to allow about 20 seconds for the temperature to be read from the moment it is turned on. These thermometers typically measure temperatures from 50 ° to 130 ° and are inexpensive.

To achieve accurate readings, we must place the thermometer in the meatiest and least greasy part of the piece of meat, away from the bone. In the case of whole poultry, we must insert the probe in the place where the thigh adheres to the trunk, since it is an area of ​​thick meat that will take longer to cook.

We should not spend pricking the meat too often to avoid losing too much juice.

PROBE THERMOMETER

We generally find them in a digital version and it warns us with an acoustic signal when the temperature reaches the correct point. If equipped with a wire probe, this thermometer can even be used in the oven to monitor the temperature at the heart of the preparation (in the oven the plug remains stuck in the meat and the measuring unit remains outside, connected to the probe by the cable, heat resistant).

These thermometers can often measure temperatures ranging from sub-zero to 250-300 °, which makes them very versatile, also for yeast, for caramelizing sugar, for jams and frying. It is worth investing a few more euros, because it can be used for many preparations.

These battery-operated and therefore portable thermometers can be used if we cook outdoors on the classic barbecues.

FRYING THERMOMETER

Useful for those who don't use the deep fryer. The correct temperature of the oil makes it possible to obtain crispy and tasty fries and at the same time delicate. Controlling the temperature allows the nutritional principles and organoleptic characteristics of the oil to be kept unaltered, avoiding the burning of fatty acids, which are the ones that provide us with great health benefits. Specific thermometers for frying are designed with a clip that anchors them in the edges of pots and pans, to keep the temperature of the oil constant, rising or falling depending on the detection.

There are professionals who even inform you of the quality of the oil and when to change it.

SUGAR THERMOMETER (OR CANDY METER)

It is about 30 cm long, it is often made of glass protected by stainless steel to prevent it from breaking, to use it it is fixed on the edge of the pot. Some are equipped with a special hook that holds them vertically in the center of the pot, facilitating mixing during cooking.

It is very useful to measure the temperature of sugar and for the preparation of caramel, it is also used to measure the temperature of liquids such as syrups, tea or milk. The temperature range is usually between 70-80 and 180-200 °. In the case of sugar, a few degrees of difference are enough to change its state, so precision is basic.

It is important to remember never to add cold ingredients or even at room temperature to hot caramel, to avoid splashing: if we prepare creams such as caramel or salted caramel, the cream or milk must be heated well before adding them to the caramel.

CHOCOLATE THERMOMETER

Similar to the classic household thermometer, but made of high heat resistant plastic. It is a perfect thermometer for those who want to temper chocolate. Extremely accurate, it measures temperatures from -20 ° to + 50 °.

Once done, the ideal temperature to store the chocolate is between 15-20 °. If we put it in the fridge we will see that it takes on a white patina, which gives it the cocoa butter when it emerges.

DOUGH FERMENTATION THERMOMETER

Those who are panarras or like to make their own cakes will know that baking and confectionery are an exact science (you have to measure the temperature of the water, the flour, the salt where the fermentation will take place and that of the sourdough end) and they probably already have their kitchen thermometer. For a good start to yeast, in fact, the dough should have a temperature between about 25-26 °. If we use sourdough at too low a temperature it will slow it down, making it inactive.

If a yeast cake is kneaded by hand, the yeast is dissolved in a liquid (water or milk), the maximum temperature must be 40 °. Fermentation should take place in a warm place, within 30 °; if the temperature is too high, it will “speed up”, with the consequent risk of bacterial contamination and developing an acid taste in the product that will remain even after cooking.

If you prepare a delicious panettone, remember that it is essential never to exceed 26 ° of temperature of the dough (so as not to spoil its sticky consistency).

WINE THERMOMETER

Controlling the serving temperature of wine is important to better appreciate its characteristics and qualities.

The wine thermometer is the ideal gift for your fans.

The temperatures that are considered optimal for serving wine are:

• Dry sparkling wines 4-6 ° C
• Sweet and sparkling sparkling wines 6-8 ° C
• Young white and rosé wines 8-10 ° C
• Structured white wines, dessert wines and fortified white wines 10-12 ° C
• Structured rosé wines and delicate reds with little tannin 12-14 ° C
• Red wines of medium structure and tannins, dessert wines and red liquor wines 14-16 ° C
• Evolved red wines with great structure and tannins 16-18 ° C

YOGURT THERMOMETER

It consists of a classic probe that ends in a small digital thermometer, to be used by immersion. For optimal fermentation of homemade yogurt, 40-45 ° are needed. If we are making cheese, it is ideal for measuring the temperature of the milk. The cost is generally low.

NON-CONTACT THERMOMETERS

Non-contact thermometers are often used by kitchen professionals. Their great advantage is that they allow the temperature to be measured without coming into contact with food, recording the infrared radiation emitted by a body. Infrared digital thermometers are also called pyrometers.

Laser-operated ones are also available: both types allow you to control the temperature of surfaces without touching them.

It should be noted that measurements do not work through glass, for example the oven glass. Its use is very widespread in pizzeria ovens, pots and pans, to measure the temperature of the water and the outside of the food that is being cooked. There are also digital infrared thermometers with a built-in probe to measure the internal temperature of food.

CLEANING AND CARE OF FOOD THERMOMETERS

After using the kitchen thermometer, we must wash the metal part that has come into contact with the food simply with hot soapy water.

In the case of sugar thermometers, a good trick is to fix it on the edge of a pot with boiling water and let it rest for a while, to eliminate the residual sugar. If we have used a thermometer probe for candy or a similar recipe, we must submerge only the metal needle in the pot.

Thermometers are only going to be useful to us when they maintain their precision, hence we have to take care of it. When in doubt, a good way to know if the thermometer is measuring correctly is to put it in ice water or boiling water. If the water is cold it should show 0 ° and in the case of boiling water it should show 100 °.

Using thermometers in the kitchen allows us to save many mistakes, obtaining great results. You sign up?

Digital Thermometers

 Digital Thermometers

A digital thermometer is an instrument that, like all thermometers, is used to measure temperatures. However, this does not mean that it is equal to all instruments intended for the same purpose.

The digital thermometer uses electronic circuits that convert voltage variations into figures that appear on a display. This works thanks to a thermistor that varies its electrical resistance depending on the temperature.

There is more than one type of digital thermometer; These are intended for various purposes. For example:

Thermocouples.
These record the temperature of food very quickly, between 2 and 5 seconds. They are available in different formats but the probes are the most required for cooking food at an industrial level, as well as for medical research.

Thanks to this instrument it is possible to know the exact cooking point of the meats in order to guarantee safety and quality.

Thermistors
These thermometers use resistance temperature sensors. Thermistors are of two opposite fundamental types:

NTC: resistance decreases as temperature increases.

PTC: resistance increases as temperature increases.

There are bead type thermistors, SMD type, disk type, axial and measuring probes.

Thermometer with cable for ovens. It is very common in large kitchens. It allows you to check the temperature of the food inside the oven without having to open it. A probe is inserted into the food and the cable runs from the oven to the base unit. Of course, it can withstand high temperatures. The only downside is that they cannot be calibrated.

Fork thermometer.
It is also a highly required instrument in industrial kitchens, as it measures the temperature of food. The fork part is embedded and the temperature is indicated on a digital display. The lights will indicate if the food is undercooked, if it has taken too long or if it is just cooked. As in the previous case, the forks of the thermometer cannot be calibrated.

Homemade digital thermometers.
Doctors recommend that our first aid kit contain a digital thermometer for fever cases where it is required to continuously measure the affected person, in such a way that medical attention is given at the indicated time.

These types of thermometers come in various presentations, suitable either to be placed between the armpit, in the mouth or in the rectum. The armpits are less accurate but the most hygienic. Oral ones are more accurate and are recommended for young people and adults, as the mouth is required to be closed and the thermometer does not move from its place for 40 seconds. Rectals are recommended for babies or young children.

Digital thermometers record the temperature quickly and efficiently, taking about 1 minute to give the result. The only specification is that orals should be applied at least 15 minutes after eating, as the temperature of the food or drink could alter the result.

Before using the oral thermometer, your hands must be clean, just like the thermometer. It is recommended to clean it with alcohol and then rinse it with cold water, dry it and store it. It is not convenient to immerse them for hours in liquids to disinfect them. The thermometer is placed under the tongue.

Those with the armpit are placed under the arm, so that when it is lowered it puts pressure and prevents it from falling. Some emit a beep when they have finished registration, but preferably the device should be held for up to 2 minutes.

Digital ear thermometers.
These thermometers use an infrared beam to measure the temperature inside the ear canal. Its use is safe, as long as the instructions are followed correctly, although it should be noted that its design prevents it from being inserted too far to avoid damage to the eardrum or ear canal.

They are not recommended for newborns, but for babies older than 6 months, children and adults.

Digital pacifier thermometers.
If a baby is in the stage of using a pacifier or pacifier, this thermometer is ideal, as it will not cause discomfort or strange sensation. However, it is not recommended for newborns, only for young children who can keep it in their mouth for 3 to 5 minutes.

Temporal artery thermometers.
They are also known as forehead thermometers and they use an infrared scanner to measure the temporal artery in the forehead.

They quickly record the temperature and are appropriate for babies over 3 months and children. It is the best alternative to rectal thermometers. The only disadvantage is its high cost, compared to other types of digital thermometers.

Plastic strip thermometers.
These plastic strip thermometers are marketed as an alternative for babies and children due to their easy handling and application, but they are very inaccurate and are not recommended by professionals.

It should be mentioned that the same thermometer should not be used in all parts of the body. This means that a rectal thermometer should not be used for the armpits, much less for the mouth, even if it has been disinfected. It is important to label them and know that it is for personal use.
