Description

Technical Field

[0002] Before the precious metal thermocouple is calibrated, it needs to be cleaned and annealed in a thermocouple cleaning and annealing cabinet. The purpose of annealing a new thermocouple is to eliminate the stress of the thermocouple, and the purpose of annealing an old thermocouple is to remove the contamination on the surface of the thermocouple, improve the thermoelectric performance and extend the service life. The thermocouple annealing cabinet adopts the principle of power annealing, hangs the thermocouple on the bracket, slowly adjusts the current size, and gives a certain current to keep the thermocouple at a certain temperature for a certain period of time.
