Copper and nickel T thermocouple _ instrument
Copper nickel T thermocouple copper -
Copper and nickel T thermocouple this is a cheap metal thermocouple, with copper as the anode, cathode copper nickel, its index number for T.
Because of the heat copper electrode extremely easy oxidation, generally should not be used in the oxidizing atmosphere more than 300 ℃.
The thermocouple thermoelectric potential rate is bigger, the thermoelectric properties is good, the material quality of a material is uniform, the cost is low, but poor reproducibility.
