WRR-120B assembly-type thermocouple with stainless steel junction box
As the sensor of the temperature measurement, assembly-type stainless steel junction box thermocouple is used with displays, recorders and electrical adjuster completely. It can measure the temperature of liquid, vapor, gas and the surface of solid from 0℃ to 1800℃ directly. According to national regulation, we have manufactured copper- copper nickel, iron-copper nickel etc. type of thermocouple since 1987. They are all not only in line of IEC international standard graduation but also JB/T9238-1999 standard.
