Short description of Infrared Digitial Thermometers

An infrared Thermometer is a device to measure the temperature by using the lens to focus the infrared from a target on a detector. This detector is known as thermopile (Thermocouples connected in series or parallel).

The infrared radiation gets absorbed by the thermopile and converts into heat. Subsequently, voltage is produced in proportion to the infrared energy. The thermopile uses this output to regulate and determine the temperature getting displayed on the screen.

Uses of IR thermometers

 IR thermometers are used for the following purposes 

  • As a clinical thermometer to measure the body temperature of human beings.
  • In the veterinary hospitals to measure the temperature of animals.
  • In industries to measure the process temperature.

benefit of using an IR thermometer

An IR thermometer being the non-contact object has the following benefits.

  • Protects the germs from spread 
  • Frequent washing is not required
  • It is convenient to use the thermometer to measure the temperature of small babies in their sleeping condition
  • In foundries to measure the high temperature of molten metal and in power plants for the measurement of exhaust temperature

The ideal distance for using an infrared thermometer

The distance for using the IR thermometer will depend upon the type of application. For the measurement of human and animal temperature, the distance of 6 inches will be sufficient, but to measure the process temperature in industry, the distance will vary. IR thermometer distance range is adjustable and can be adjusted for the type of application.

Accuracy of infrared thermometers

The accuracy of the IR thermometer will depend upon the following factors

  • Quality of product
  • The way of using and maintaining the appropriate distance
  • Condition of battery. A weak battery will not give the correct measurement.

Time taken by an infrared thermometer to display the results

Usually an IR thermometer doesn’t take much time to display the reading. In most of the IR thermometers results are displayed within 5 to 6 seconds. This is the main reason for the use of these thermometers at the entry gates of public places.

IR Digital Thermometers Buying Guide

Consider the following points before buying the IRDigital Thermometers.


Accuracy is the most crucial factor to be considered during the purchase of a thermometer. The accuracy of any IR Thermometer will depend upon the Distance tosspot ratio denoted as D/S. This distance will indicate the maximum distance from where the thermometer will be able to evaluate a targeted surface area.

Temperature range

The temperature range is the maximum range of the thermometer within which the measurement displayed will be nearly correct. As per the studies and experience it has been found that the narrower ranges produce better and accurate results for the higher resolutions. Temperature ranges will differ as per the type of IR Thermometers.


The amount of infrared energy put out at a time by an IR thermometer is known as the Emissivity of the thermometer. The Emissivity near to one will read more materials than the thermometers with lower emissivity value.

Response period/ Reading Speed

Response period is the time taken by an IR thermometer to display an accurate reading after initiating the measurement process. The importance of this factor is essential for the use of moving objects and quickly heating objects.


The design of the industrial Thermometer has to be more rugged than the clinical IR thermometers. The most durable Thermometers are with no-lens and Fresnel lens, due to the polymer structure for keeping the thermometer safe. Tough mica lens will always need a durable box and carrying case, to prevent the lens from damage by cracking.

Backlit Display

Screen with a backlit display will be easier to read the thermometer in any given condition.

Warranty (The Best top 10 IR Digital Thermometers in 22)

Always look for the manufacturer’s warranty since the thermometers are more fragile and are equipped with an expensive lens.
