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? "
