                     How do Infrared Thermometers 
Work?

In the category of thermometers, contactless infrared thermometers are 
paramount, especially in the current scenario. Gone are the days when a caregiver or 
doctor had to stick a thermometer under the tongue to measure the temperature of 
the human body. With technological and scientific advancements, contactless infrared 
thermometers are increasingly being used as they are portable, light, handy and 
hygienic. 
Contactless Infrared thermometers can measure temperature from a distance. The 
distance can be from a meter to a few miles. However, 1-meter distance is just apt. 
The first infrared thermometer to be commercially available was produced in 1931. 
Infrared thermometers work under a basic principle: All the things that have mass 
radiate energy in the form of heat. The infrared thermometer can detect the infrared 
(IR) rays by detecting the heat being emitted by the object against the backdrop of the 
surrounding. The IR rays are further funneled into a detector called a thermopile. In 
the thermophile, the IR gets converted into heat and then into electricity which is 
measured.
The thermopile becomes hotter with rising infrared energy. The amount of 
electricity generated by the rays reflecting from the object provides a reading that is 
then displayed on the thermometer. One can see the reading being displayed on 
the infrared thermometer within seconds.  Because of its fast deliverance of results, 
it is used in medical and commercial setups. 
This phenomenon is also called black body radiation. The hotter the molecules in 
an object get, the more they emit IR rays. In turn, the intensity of the electricity 
depends on how hot the object is. 
The infrared thermometers have a good reputation for accuracy and are highly 
reliable. They are a safe equipment to use as they ensure safe distance. One must 
aim the infrared thermometer at the object or person from a distance and the 
reading would be shown in a few seconds. This also solves the issue of plausible 
contamination or cross-contamination. Moreover, it is durable whether used 
extensively in a clinic, hospital, at home or at airports.  Apart from this, there are 
multiple uses of infrared thermometers.You can
