Production and scientific experiments often need to accurately measure and control the temperature. In order to accurately measure and control the temperature, we must have a correct understanding of the characteristics and measurement methods of various temperature sensors. Therefore, the measurement of temperature characteristics of temperature sensors is one of the important experiments of basic physics experiments in Colleges and universities.
