  • Introduction
  • Specifications
The industrial assembly-type thermocouple is used as a sensor of measuring temperature, always being used with display instruments, recording meter and electronic regulator. It can be directly measured the surface temperature from 0 oC to 1800 oC within liquid, vapor, gas medium and solid which from various production processes.
 
 Since 1987, according to the national regulations, our factory have being producing thermocouple made from Pt-Rh /30%, Pt-Rh /6%, Pt-Rh /10%,Ni-Pt, Ni-Si, Ni-Cr, Cu-Ni, Fe-Cu-Ni etc under the IEC international standard index numbers, and also comply with JB/T9238-1 999 standard.
