Buying Guide To Know The Complete Information of Infrared Thermometer

Infrared thermometers have a wide range of applications due to their ability to measure accurate temperature from a distance. They have medical industrial and many other vital uses. You need to know the below information before you plan to buy one.

Factors To Consider While Buying

The factors to consider before buying an IR thermometer are as follows.


Each object has surface texture and a returning capacity of the energy emittance. As IR thermometers measure the temperature using the energy radiated, the relative emittance of the surface plays a significant role in accurately determining the temperature. Hence IR thermometers with emissivity adjustment are a good pick, and this adjustment usually provided for an industrial applications-based thermometer.


Every IR thermometer has this value, and you need it to determine how much distance the 1-inch measuring spot forms. That will be the base measurement for expanding the area of coverage or pinpointing the field of analysis by moving forward or backward in the given range of distance.

Temperature Range

The temperature range is high for industrial usage and low for medical usage as the needs differ, so do the values.


Not all thermometers are useful for every use. There are considerable machines to simple handheld devices based on the IR related to temperature. However, we get to use very few types in our daily life at home and work. Determine the use of it and then buy it. High range temperature thermometers differ from the low range devices in their uses.

Special Features

Backlit display, alarm, customization, color light, etc., are fancy special features available to enhance your user experience. They may come with an additional cost. So, weigh the pros and cons of such an arrangement and buy them only if they are no burden on your pocket.

Types Of IR Thermometers

Though IR thermometers can be classified based on many factors, the most crucial factor is the lens through which they emit the IR rays. Based on the lens, there are three critical types of IR thermometers.


These IR thermometers are pretty small and do not have any lens. They just force the light into a small area using a funnel-shaped reflective surface. They are inexpensive and accurate, but the downside is they cannot withstand high temperatures and cannot measure from longer distances.

Fresnel Lens

These are the lens made of plastic and are easily distorted when subject to extreme temperatures and require little in between resting time. Their temperature range is low but adequate for food-related measurements and usually uses in restaurants.

Mica Lens

Industrial grade lens that withstands high temperatures and is expensive. They can work with much farther distances than the above two IR thermometers.

Benefits of IR Thermometers

IR thermometers are a boon to several services. Listed below are their few uses of many.

  • No-contact body temperature measurement avoiding cross-contamination
  • Measuring scorching body surface temperatures from a distance without danger
  • Finding out electrical faults using the hot spot technology focused on overheating of components
  • Identifying insulation issues
  • Knowing the temperature of barbeque grills
  • Measuring the coolness of a fridge
  • Identifying the temperature of pool water

There is an endless list of possibilities, and you will find a new use every day once you own an IR thermometer. It does not only sort out serious stuff but also helps in having fun.

Frequently Asked Questions (FAQs)

Below are some interesting questions that will help you understand better about IR thermometers.

Are infrared thermometers accurate?

Yes, Infrared thermometers are accurate. However, this depends on the apt usage of suitable thermometers for the proper need. Though all thermometers using IR technology are called IR thermometers, they are not the same. It is just a broad classification of an extensive range of devices. Industrial IR thermometers cannot measure the temperature of human bodies or animal bodies as designed for inanimate objects only. So is the case with medical thermometers that cannot catch the high range temperatures as the scope of the medical thermometers is limited.

Can I use an infrared thermometer on a person?

Yes, but not all infrared thermometers are suitable for this purpose. These generally come under medical IR thermometers and have limited uses like measuring body temperature and everything else that falls between the range of the high low temperatures of the medical thermometer. Since its range is low, it cannot measure high heat-emitting objects or icy objects. So, this is where the industrial IR thermometers come into play. Industrial thermometers cannot accurately read body temperature as they do not deal with objects in motion.

What is essential to check on a good IR thermometer?

Accuracy, emissivity adjustability, temperature range, distance to spot ratio, and resolution are essential to check for finding a good IR thermometer. Accuracy value should have the least possible error deviation, emissivity adjustability should be flexible and adjustable as required, and high and low measurement range should be according to your requirement. Distance to spot ratio considered as per your usage of how far or high things you need to measure, and the resolution help give precision accuracy.

How do I use my infrared thermometer?

You just need to point at the object from a specified distance range based on the thermometer model specifications. Then click the button you will get the temperature readings within the response time of that thermometer. Some models need few settings like emissivity adjusted for accurate temperature. For such thermometers instruction of setting proper values are provided in the manual of you can have plenty of information online. Usually, industrial need-based thermometers have these complicated settings, but medical IR thermometers have fewer settings and mostly come with predefined values and buttons for easy usage.


You require a digital laser infrared thermometer then this is the proper place to know everything you need to know about IR thermometers. Form how they measure surface temperatures to show you many more unimaginable ways you can use them. Every detail provided so that you find this guide comprehensive and the products to be of high quality.
