  • Products display

Since 1993 we have manufactured nine types of thermocouple assemblies and RTD assemblies: B, R, S, K, E, J, T, N and Pt100, which meet the requirements of IEC standards.Measured temperature range is -40 to 1600℃, according to the use temperature, choose the wire diameter form Φ0.3mm to Φ3.2mm .

◆ Thermocouple assemblies and RTD assemblies

 

    Industrial assembly thermocouple is used to measure the temperature of the sensor, it can directly measure the 0-1600 range the various production process liquid, steam, gas medium and solid surface temperature. The foundation of national regulations, my factory finished in accordance with IEC international standard indexing number T, J, E, K, N, S, B type thermocouple.
