Immersion thermocouple(Type S,R,B and Wre):
Expendable thermocouple(R,S,B,and Wre)is usually connected with display meter,recording meter and computer,etc.to directly measure temperature of liquid metal ranging from 0-1820°c during various steel or iron process.
It has advantage of high accuracy,rapid reaction,reliability and stability.
According the different thermocouple wire,thermocouple has four type are S,R,Band WRe Type.
