Product description:
WGG2 type optical pyrometer
A, the product description
WGG2 type optical pyrometer is a non-contact measuring instrument of high temperature, when the measured temperature is higher than the scope of the thermocouple can use and the thermocouple device impossible or inappropriate place, using optical pyrometer generally can satisfy this requirement.
It is widely used to measure the smelting, casting, rolling, glass melting kiln, forging, heat treatment temperature, metallurgy, chemical industry and machinery, and other industrial production one of the indispensable in the process of temperature measuring instrument.
Second, the main technical indicators
· WGG2 type optical pyrometer can in 10 ~ 50 ℃ environment temperature, relative humidity is not more than 85% under the condition of continuous work.
The objective lens and the distance between the target is not less than 700 mm.
Scale length not less than 90 mm.
About 1.8 kg net.
