The national standard of testing K type thermocouple is what?

Standard k type thermocouple is refers to the national standard specifies its thermoelectric potential and the relationship between temperature, permissible error,

and a unified standard score table of thermocouple, it has with matching display instrument to choose from.

the structure of thermocouple thermocouple is reliable, steady work, to ensure that the requirements for its structure is as follows:

(1) of the two thermocouple thermal electrode welding must be strong;

(2) the two hot electrode should be well insulated between each other, in case of short circuit.

(3) compensation conductor should be connected to the free cod of a thermocouple to be convenient and reliable;

hot electrodes (4) protect casing should be able to make sufficient isolation and harmful medium.
