Optical pyrometer is a non-contact instrument for measuring high temperature. When the temperature to be measured is higher than the range that thermocouples can use, and where it is impossible or not suitable for installation of thermocouples, optical pyrometers can generally meet this requirement. It is widely used to measure the temperature of smelting, casting, steel rolling, glass melting cellar, forging and heat treatment, and is one of the indispensable temperature measuring instruments in the industrial processes of metallurgy, chemical industry and machinery.
WGG2-201 optical pyrometer can work continuously under the condition of ambient temperature 10～50℃ and relative humidity not more than 85%.
