Pyrometers are a class of non-contact thermometers that measure the temperature of a surface by detecting the thermal radiation emitted by it. Radiation thermometers are essentially pyrometers. They are commonly used for measuring very high temperatures or temperatures of objects that are inaccessible or hazardous to touch.
