How to use the thermocouple

In order to ensure the accuracy of the measurement result, the probe of the thermocouple should be inserted into the bottom of the protective tube to fully contact the measured object.

The connection of thermocouple and the instrument requires the use of compensation lines with the thermocouple, and it is necessary to clearly distinguish the positive and negative poles. Otherwise, the measurement results will be inaccurate.

It should protect the thermocouple and thermocouple wiring box to prevent the thermocouple from being polluted, and it should be stored in a sealed environment in time.

The insulation material should be complete. In the use of thermocouple, if the insulation material between the two thermal electrodes is poor or short -circuit, the measurement results will be errors or cannot be measured. Therefore, it is necessary to ensure that two thermal electrode is separated through the insulation material
