What are the differences between thermal resistance thermometer calibration way

Thermal resistance of the fixed-point method mainly through the main definition of thermal resistance on the international scale temperature, it is concluded that the protection degree of resistance to ensure that the main way, normally use more temperature protection is triple point and freezing point of metal, if is high temperature basic USES the freezing point of the metal, the low temperature basic use metal triple point or a low temperature furnace.

when using high and low temperature thermal resistance furnace of metal solidification point for verification, because the metal in the process of the whole coagulation is easier to appear too cold, so at the time of verification, should first determine whether good thermal resistance of the temperature in the normal temperature, can the normal resistance value of the correct measurement. But if is to use the fixed point method for verification, the advantage is that can better accuracy, but this way need more airtight container, and the actual operation is complicated, not only a long time and the price also is bigger, so normally won't use this is verification method. The above content thermal resistance are mainly introduced in the verification of the thermometer, hope can bring you help, more information on the thermal resistance can login our company website, thank you!
