How to choose your infrared thermometer

To find the infrared thermometer that best suits your needs, here are some criteria to consider:

#1 - Temperature range

Think about the temperature range you need for your use. For example, if you plan to use your laser thermometer only for medical use, or for everyday use around the house (to measure surface temperatures of your grill or air conditioner), you may not need a wide temperature range. However, if you plan to use your infrared laser thermometer when working with machinery, engines, or in an industrial environment, a higher temperature range may be more relevant.

If you're looking for the best infrared thermometer for pizza ovens, for example, you'll need a thermometer that has a temperature range that can go above 400°C. HVAC (Heating, Ventilation, Air Conditioning) repair work, on the other hand, will require a more precise temperature range: from about 4 °C to 50 °C or higher.

And if you're looking for the best infrared thermometer for measuring human body temperature, a temperature range that goes from about 34°C to 41°C should be sufficient. But it should offer much greater accuracy than industrial infrared thermometers.

#2 - Accuracy or sensitivity

Accurate measurements are vital, especially when you're working with expensive machinery or in a commercial kitchen where accuracy is paramount. For example, when using a digital model in food safety applications, you need a specific, accurate reading every time. Check the specifications of your model, because the more accurate it is, the better your results will be.

So the accuracy and sensitivity you need will depend on how you want to use your thermometer. The best infrared thermometer for humans, for example, will be accurate to within 0.1° of error. If you're looking to measure heat buildup on your car tires, however, an error of +/- 2% or several tens of degrees is perfectly acceptable.

#3 - Target distance ratio (D:S ratio)

This is the ratio of how far you can measure a surface to the area of the surface that the infrared thermometer will measure. For medical infrared thermometers, a ratio close to 1:1 may be sufficient, as they are usually held a few inches from the forehead or ear. If you're looking for the best infrared thermometer for work in a commercial kitchen, automotive repair, or HVAC work, you'll need a much higher ratio to be able to measure surface temperature at a comfortable distance.

#4 - Emission

Emission refers to the ability of an object or material to emit infrared energy, which IR thermometers use to measure the temperature of an object. Emissivity values range from 0, for a perfectly reflective surface, to 1.0 for a perfectly absorbent surface.

Infrared thermometers with a fixed emissivity setting of 0.95 will be suitable for high emissivity surfaces, meaning that the surface will effectively radiate the temperature of an object. They will work well if you need to measure the temperature of dark matte surfaces such as asphalt, walls or tiles.

Fixed emissivity settings will cause problems when measuring reflective surfaces with low emissivity ratings, for example, measuring polished metal will give false readings when the emissivity settings are not adjusted. A thermometer with adjustable emissivity settings (between 0.10 and 1.00) will be more accurate because you can calibrate the thermometer for each surface you measure.

How to use an infrared thermometer

Turn on your device. Make sure it is set to degree Celsius mode. Some thermometers actually also offer a degree Fahrenheit mode setting.

Read the instruction manual to make sure you are familiar with the D:S ratio (target distance ratio) of your device. This will provide better accuracy when taking measurements. As a general rule, the closer you are to a surface, the more accurate the measurement. However, keep in mind that it can be dangerous to get too close to extremely hot objects.

If your model's emissivity is adjustable, go ahead and change the emissivity to the optimal setting for the surface you are trying to measure.

With laser guidance, point your thermometer at the object you want to measure and pull the trigger to display the temperature on the screen. Try to choose a location on your surface that is not too close to other objects with very different temperatures.

Do not use your device to measure objects with highly reflective or shiny surfaces without adjusting the emissivity. Do not attempt to use your instrument to measure objects behind smoke or glass as the thermometer will measure the temperature of the smoke or glass instead.

The different types of infrared thermometers

Infrared thermometers for medical use

Medical infrared thermometers allow you to measure the temperature of the human body more quickly and with less risk of contact with infectious fluids or particles than traditional mercury thermometers. They are an excellent alternative to mercury thermometers which are now banned from sale (too harmful to health). Medical infrared thermometers are not harmful to health, and they are not invasive.

There are mainly two types of infrared thermometers: forehead thermometers (without contact) and ear thermometers. The connected version of this type of thermometer is starting to gain popularity today. Indeed, they improve temperature monitoring of babies and help reassure parents.

Infrared thermometers for non-medical use

Non-medical non-contact infrared thermometers allow you to measure temperatures of very hot objects without the risk of burns or property damage. It is a device that will therefore allow you to measure the temperature of an object at a distance and with great accuracy. This type of thermometer is particularly useful for measuring the temperature of a moving object.

Infrared thermometers for non-medical use are therefore intended to be used for measurements that require very short response times, and which must be done at a distance. For the control of packaged food products, for the verification of mechanical equipment or electrical circuits, for the control of the heating or cooling of materials with precision. And even for the detection of hot zones during a fire.

Infrared thermometer or traditional thermometer?

Infrared thermometer

The infrared thermometer is perfect for situations where you cannot directly touch the target you need to measure, whether it is an object or a person. This type of thermometer is much safer: the non-contact option is safer. It allows you to take measurements much faster and can usually measure a wide range of temperatures.

They do not, however, allow for internal measurements, and cannot measure all surfaces equally well (e.g., shiny metals are more difficult to measure).

Traditional thermometer

By traditional thermometer we mean the one that is made of glass to clearly see the temperature. It is thus composed of a bulb with a long capillary tube to contain the liquid. This liquid is usually gallium or alcohol, they have replaced mercury, too toxic and now banned in many countries. This type of thermometer is suitable for measuring low temperatures, because the freezing point of the liquid is generally low. It is also more accurate than infrared thermometers.

Its main disadvantage is that it must be left in place for at least 5 minutes to be effective. It is also more fragile, and can expose the user to risks in case of breakage.


Infrared thermometer or traditional thermometer, the choice is yours. However, if you are more comfortable with a non-contact measurement that takes only a few seconds, an infrared thermometer is right for you. But if you are more comfortable with precision, a traditional thermometer will suit you better.

6 reasons to buy an infrared thermometer

  1. Quick Readings: Infrared thermometers provide quick and easy temperature readings that are also very accurate. The whole process is hassle-free because the thermometer works like a handheld scanner. Just point it at a subject (human or not) and you're done.
  2. Usable in the dark: They usually come with an illuminated LED screen that helps to record readings even in dark environments. The bigger the screen, the better your reading experience.
  3. Non-invasive and more hygienic: This is especially true of fever thermometers. They are very beneficial because they make it easy to record a baby's temperature while he or she is sleeping, for example. Or to take the temperature of a fearful child without stressing him too much. The whole process is simple and non-invasive, as it does not require instantaneous contact for accurate temperatures. It therefore limits the transmission of contagious diseases.
  4. Safe: This applies especially to infrared thermometers for non-medical use. The fact that it is possible to take the temperature without contact limits the risks of accident. Indeed, no need to get too close to a hot surface to know the exact temperature.
  5. Multiple uses: Thermometers have multiple uses, because they can record other temperatures. For a clinical thermometer, it can also be used to check baby's bath water, or formula water. This feature ensures a steady supply of milk at the right temperature for your baby. And for a non-medical thermometer, it can be used to check the temperature in the kitchen (of the frying pan, of the oil on the fire, etc.), as well as the heating, etc.
  6. Cost-effective: this type of thermometer is not more expensive than any other, so it is easily accessible to everyone. Its use generates impressive energy savings, especially for parents who had to struggle to take their child's temperature before. It also saves an incredible amount of time, especially in the commercial and industrial fields.

Check if the thermometer is suitable for medical use

Some infrared laser thermometers are intended exclusively for use on non-living objects and surfaces. Never use such thermometers to measure body temperature, as this could cause accidents. Indeed, the laser used in this type of thermometer can be more powerful, with risks of burns to the skin and especially the eyes. Before using an infrared laser thermometer, read the instructions for use properly and confirm that it is suitable for medical use.

Be careful with children

If you have to use an infrared thermometer with children around, you have to be very careful: make sure they do not get the laser in their eyes. Thus, for the medical thermometer, prefer infrared ear thermometers. Since they go into the ear, there will be less risk of burning the child's eyes with the laser.

Keep the laser beam away from the eyes

It cannot be repeated enough, laser beams are dangerous when misused, let alone when directed at the eyes. They can cause serious injury or even blindness. Be very careful when using an infrared laser thermometer: make sure the beam does not touch your eyes or the eyes of anyone nearby.

Always keep the cover in place

To avoid pointing the laser beam at unwanted surfaces, keep the cover in place when not using the thermometer. Be very careful when opening the cover before measurement. As soon as you have finished measuring, replace the cover and store the thermometer in a cool, dry place. Protect the thermometer from moisture, dust, and excessive heat so that it can function properly.

Release the trigger or button after measurement

All infrared laser thermometers have a button or trigger that you must push to start the operation. Remember to release the button or trigger after you finish taking a measurement. Not doing so will shorten battery life, and the laser beam may also hit people or other objects that do not need to be measured.

Be careful around reflective surfaces

If the laser beam hits a reflective surface such as a mirror, it can reflect back and hit you or someone else nearby. Therefore, proper planning and positioning are essential when using the device, especially if it is not for medical use, near a reflective surface. In any case, keep young children away as a priority in this case.

Use the thermometer in an area free of explosive gases

If a laser beam strikes an explosive gas or combustible surface, it can cause an explosion. Never use the device near combustible liquids or gases to avoid fire or explosion.


What is the most accurate infrared thermometer?

To put it simply, these are the clinical thermometers. But really it depends on what you want to use them for. Medical thermometers offer high accuracy (of 0.1° or less than 0.1%), compared to industrial infrared thermometers that offer a 2-3% variation in accuracy. However, medical thermometers have a very inadequate temperature range for other uses.

Are they really better than traditional thermometers? Are infrared thermometers safe? How to test the accuracy of the infrared thermometer? Can infrared thermometers work through glass?

The answer is yes. Infrared thermometers are accurate, reliable, and have a variety of uses for which they are well suited. If you need to buy a thermometer, whether for home use or industrial use, this type of thermometer is highly recommended.

They can be used safely. They allow you to measure temperature with a safe distance. For humans, as long as the laser beam is not directed into the eyes, the infrared thermometer is perfectly safe for everyone - babies, children and adults.

Use ice water: fill a glass with ice cubes and add enough water to fill the spaces formed between the ice cubes. Stir several times for an even surface. Point your infrared thermometer directly at the surface of the ice water from a distance of less than 5 cm. Make sure the thermometer lens is at a 90° angle and the laser is pointing at the center of the surface. Record the temperature at this setting. If your infrared thermometer reads about 0°C, your device is within the specified accuracy.

Infrared thermometers cannot accurately measure temperature if there is glass, liquids, or any transparent surface between the subject and the thermometer. The temperature values displayed under such conditions are those of a transparent surface, not the target.
