WREK,WRNK,WRCK armored thermocouple
Armored thermocouple is good at bending, anti-high temperature and fast heating response. As the sensor of the temperature measurement, it is usually used with the displays, recorders and adjustable meters completely. At the same time, it also can be the heat responsive element of the assembly-type thermocouple to measure the temperature of the liquid, vapor, gas and the surface of solid from 0℃～800℃ directly.
