- Jan 02, 2018 -

Thermometer before use need to test, the general procedure is the first thermometer at the specified temperature and time heating, and then let the thermometer slowly cooled, and then fixed at a few points in the temperature side of the New Zealand electric suction value. This process is repeated several times, according to the resistance of the resistance meter changes to assess the characteristics of the thermometer. The heating is gradually increasing, and after each increase, the resistance of the thermometer is measured at the water triple point, the zinc freezing point and the tin freezing point, and is often measured at the freezing point of gold, silver and aluminum, in addition to being subjected to special tests Into the depth test and leakage test.
