How to Choose an Infrared Thermometer

An infrared thermometer measures the temperature of material using infrared radiation. These devices come in different designs and features. We’ll go over their Field of View, Limitations, and durability. You can decide whether or not you want one for your needs based on these features. Here’s how to choose an infrared thermometer:


Infrared thermometers are used for body temperature measurement. They are based on the principle of thermal equilibrium, in which the changes in temperature of an element are converted into a measurable electrical signal. Infrared thermometers can also be used for temperature measurement in sealed cavities. Currently, standard CMOS processes are used to fabricate IR sensors. These technologies have already been proven effective in developing SOC technology. However, future research and development are expected to focus on enhancing the sensitivity of CMOS-MEMS IR sensors and realizing high heat radiation absorption technology. infrared thermometerSeveral applications for an IR thermometer are listed below. For example, firefighters use these instruments to locate hotspots in fires. Similarly, a non-contact thermometer can monitor industrial equipment and surfaces. These devices are also useful in monitoring engine cooling systems. In addition, IR thermometers can detect hotspots in electrical systems. Listed below are some of the most common applications of infrared thermometers.

Field of view

An infrared thermometer’s field of view (FOV) is the diameter of the spot that the instrument can see at a given distance. It is a measure of the device’s optical sophistication and depends on the distance from the target. It ranges from 1:1 on a low-cost instrument to 60:1 or more for high-end instruments. Generally speaking, the larger the FOV, the smaller the spot will be, and vice-versa.

The field of view of an infrared thermometer is critical for quality. It determines the spot’s size compared to the surface being measured. For example, a pyrometer with a 40-inch field of view will render a spot size of 0.4 inches at a distance of 100 inches. However, the value of the temperature that is measured will remain the same, no matter what the distance is.


A common limitation of an infrared thermometer is that its wavelength is limited. In addition, the device only measures surface temperatures, so it’s not the best option for determining the core temperature of objects or the temperature of various points in a heat-induced room. Luckily, there are solutions. Read on to discover some of the limitations of an infrared thermometer. Also, find out if you need to calibrate your infrared thermometer!

IR thermometers are non-contact, so they don’t exert mechanical effects on the surface of the measured object. They are also cheap and can be used to measure objects that are too hot or cold to be reached with other methods. However, you should carefully target your measurement. You can only obtain an accurate reading if the measurement surface and the device are in the line of sight (LOS).


An infrared thermometer is an answer if you need a reliable and accurate thermometer for your automotive, HVAC, and mechanical repairs. The device can measure the temperature of many different surfaces, including cars, motorcycles, and air conditioners. Its IP54 rating makes it dust and water-resistant. Its small size makes it easy to clip onto your tool belt or storage area. The infrared thermometer can switch between Celsius and Fahrenheit to provide accurate readings, but not all IR thermometers can do this.

IR thermometers are generally very accurate, with an accuracy range ranging from 0.1 to 1.0. They are also highly versatile, with applications ranging from checking coffee to evaluating the temperature of motors. However, some models are not as durable as others. Unlike digital thermometers, infrared thermometers cannot be placed close to hot surfaces. In addition, because they are not so sensitive, they may be difficult to use, or the body of the device may not be as robust.

Cost thermometer, which measure temperature without touching the subject, are an excellent choice for medical professionals and home users. They reduce the risk of infectious diseases and infection because they don’t require contact with the subject. This non-contact thermometer is ideal for professional and home use and can be easily purchased online. To learn more, read about the advantages and disadvantages of infrared thermometers.

Infrared thermometers are becoming more popular with the advent of the Pandemic and their impact on the health care industry. With new technology emerging every year, the cost of these devices has decreased dramatically. With the rise of the medical industry, the cost of infrared thermometers is a growing concern for health professionals. A new technology, the Infrared thermometer, provides various benefits for the user.
