Pyrometry



Pyrometry, process of measuring exceedingly high temperatures through the use of a pyrometer, an instrument that can function in heat far hotter than that tolerated by ordinary thermometers. Most pyrometers measure temperature by detecting the rise in electrical resistance in a metal, by the increase in the intensity of light, or by similar electrical or radiation techniques.
