How to Choose and Use Infrared Thermometers - Grainger …

· Handheld IR thermometers use a lens to focus the infrared energy from an object onto a sensor that measures it, typically a thermopile. The sensor absorbs infrared radiation and converts it to an electrical signal, with more intense radiation creating a stronger signal. The IR thermometer processes this signal in order to deliver a temperature readout.

How Does A Temperature Gun (Infrared Thermometer) Work?

· 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.

How an Infrared Thermometer Works | Global Sensors

What infrared thermometers do is measure the amount of infrared radiation being emitted by the target object and compare it to the surrounding atmosphere to determine its temperature. Like visible light, infrared radiation can be focused and absorbed, and an infrared thermometer does both in order to measure temperature. The thermometer has a lens that directs incoming infrared radiation towards …
