Introduction:

Class II Standard Platinum Resistance (Aluminum Point Quartz Tube) is a standard instrument for temperature measurement based on the characteristic of the resistance value of platinum wire changing with single value of temperature. The ITS-90 International temperature scale specifies that standard platinum resistance thermometers are interpolated instruments from 13.8033K (-259.3467℃) to 961.78℃. The parameter function of standard platinum resistance thermometer 0℃-961.78℃ in IST-90 international temperature scale is determined by the characteristics of a high temperature platinum resistance thermometer used by China and Germany in Yunnan, China. Standard platinum resistance thermometers are the thermometers with the highest accuracy and the best stability when measuring temperature under current production conditions.
