WGG2-201 optical pyrometerDetailed product description：

Product Introduction:

The optical pyrometer WGG2-201 can operate continuously at an ambient temperature of 10-50 ℃ and a relative humidity of no more than 85%. The distance between the objective lens and the target is not less than 700mm, the length of the scale is not less than 90mm, and the net weight is about 1.8kg.
The optical pyrometer WGG2-201 is a non-contact instrument for measuring high temperatures. When the measured temperature is higher than the range that thermocouples can be used, and in places where thermocouples cannot be installed or are not suitable for installation, an optical pyrometer can generally meet this requirement. It is widely used to measure temperatures in smelting, casting, steel rolling, glass melting, forging, heat treatment, and other industrial production processes. It is one of the indispensable temperature measuring instruments in metallurgy, chemical engineering, and machinery.
