WRN -131 No fixing device
Brief Description
The industrial assembly-type thermocouple is used as a sensor to measure temperature, usually matched with display instruments, recording meter and electronic regulator. It can directly measure temperature from 0oC to 1800oC of liquid, vapor, gas medium and solid surface during various production processes.
Since 1987, according to the national regulations, our factory have been producing thermocouple made from PtRh30-PtRh6, PtRh10, NiCr-NiSi, NiCr-CuNi, Cu-CuNi, Fe-CuNi etc under the IEC international standard index numbers, and JB/T9238-1 999 standard as well.
