Brief Description

The WRE-520 assembly thermocouple is used as asensor to measure temperature, usually matched with display instruments,recording meter and electronic regulator. It can directly measure temperaturefrom 0oC to 1800oC of liquid, vapor, gas medium and solidsurface during various production processes.

Since 1987,according to the national regulations, our factory have been producing thermocouplemade from PtRh30-PtRh6, PtRh10, NiCr-NiSi, NiCr-CuNi, Cu-CuNi, Fe-CuNi etc underthe IEC international standard index numbers, and JB/T9238-1 999 standard aswell.
