[0002] Copper vacuum heat treatment equipment is a metal heat treatment, which is a process of placing a metal workpiece in a certain medium, heating it to a suitable temperature, keeping it at this temperature for a certain period of time, and then cooling it at different speeds to control its performance by changing the surface or internal structure of the metal material. When using copper vacuum heat treatment equipment, a furnace temperature tester is required for temperature measurement. The commonly used temperature measurement method is to use a thermocouple to measure the temperature.

[0003] At present, when a thermocouple-type furnace temperature tester is used to measure the temperature inside a copper vacuum heat treatment device, it is necessary to pre-open an installation through hole for inserting the thermocouple on the copper vacuum heat treatment device.
