Abstract: The paper involves the study on the usage of standard platinum resistance thermometers in thermal resistance verification and temperature measurement by comparatively analyzing the theoretical calculation with the data results based on the existing specifications and the experts' conclusions in China. By nominal resistance value(Rtp) for 25 Ω and 100 Ω standard platinum resistance, different tolerance levels of electrical measuring instruments were employed to measure the temperature and verify the industrial thermal resistance by means of different methods and standard platinum resistances with the nominal resistance value(Rtp) of 25 Ω and 100 Ω. The meaningful data obtained has identified and proved one misunderstanding in domestic specifications and experts' arguments. The study has great economic and social value in promoting the scientific verification method of industrial thermal resistances and enhancing the accuracy of the detection results.
