Spot Pyrometers

A spot pyrometer is a type of fixed thermal sensor used for measuring high temperatures of a surface, often in large furnaces or kilns. These devices measure the temperature of an object or surface from the thermal radiation emitted, also known as radiometry. Fluke Process Instruments pyrometers are rugged and flexible infrared sensors designed for harsh industrial environments, providing continuous visual process monitoring in a wide range of temperatures.
