How to Choose and Use Infrared Thermometers - Grainger …

2020-11-04· 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.

Infrared Thermometers Selection Guide | Engineering360

Infrared thermometers have a lens that focuses infrared light from an object onto a sensor called a thermopile. The thermopile collects a small amount of infrared radiation emitted from the targeted source and turns it into heat. The heat is then turned into an electrical signal that is amplified and converts into voltage output. The thermometer’s central processing unit uses this output to ...
