Product Features
BBZ WRR2-120B komatsu water temperature sensor made in china
As the sensor of the temperature measurement, the industrial BBZ WRR2-120B komatsu water temperature sensor made in china is used with displays, recorders and electrical adjuster completely.
According to national regulation, we have copper- copper nickel, iron-copper nickel etc. type of thermocouple. They are all not only in line of IEC international standard graduation but also JB/T9238-1999 standard.
BBZ WRR2-120B komatsu water temperature sensor made in china can measure the temperature of liquid, vapor, gas and the surface of solid from 0℃ to 1800℃ directly.
