(6) Matters needing attention:

Welding method: The metal body and the body are directly welded for welding. Do not use soldering to avoid false welding. The welding time is controlled within 3.5 seconds

Do not test the enameled wire thermistor in the air. The temperature difference in the air is large, and the measurement is very inaccurate. It often produces a deviation of more than 1-2°C. It must be measured with a high-precision constant temperature oil tank, and the measured NTC is placed in the constant temperature oil tank. After that, the temperature of the constant temperature bath must be stable before
