Non-contact temperature measurement (infrared)

Infrared thermometers are mainly used to measure temperature of a surface without making any contact. During infrared measurement (IR measurement), surface temperatures are measured without contact and also at a distance. IR measurement is ideal for moving or conductive parts. 

 
Did you know: The testo 835-T2 infrared thermometer can measure up to 1500°C.
