Temperature measurement is essential in high-temperature industrial environments such as metal forging, glass manufacturing, and furnace operations. Two common non-contact devices used for this purpose are Radiation Pyrometers and Optical Pyrometers.
While both serve a similar purpose, they operate on distinct principles and offer different advantages depending on the application.
This article outlines the key differences between radiation pyrometers and optical pyrometers, exploring the scope of each and helping industries choose the most appropriate tool.
