Application
Usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Directly measure the temperature of liquid, steam and gas media, as well as solid surface temperatures within the range of 0°C to 1300°C in various production processes.

Working Principle
The electrodes of the thermocouple are composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.

Room Temperature Insulation Resistance
When the ambient temperature is 20±15°C, relative humidity is not more than 80%, and the test voltage is 500±50V (DC), the insulation resistance between the electrode and the outer sleeve is ≥1000Ω·m.
That is, the insulation resistance of a 1m long sample is 1000MΩ;
The insulation resistance of a 10m long sample is 100MΩ;
