How Do Infrared Temperature Guns Work?

Apr 15, 2021· A temperature gun—a type of infrared thermometer—works by measuring the amount of infrared radiation emitted by an object. The emitted IR radiation is focused onto a thermopile using a lens; the thermopile then converts thermal energy into electrical energy, and finally, these electrical signals are used to determine the temperature of the body.

Infrared Emissivity Table | ThermoWorks

Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface (a black body). A black body is a material that is a perfect emitter of heat energy and has an emissivity value of 1. A material with an emissivity value ...
