Abstract
Studies on an accurate temperature measuring method were conducted, and the following results was obtained:
1) To do the accurate measurement of temperature by thermocouple effects of the room temperature effect on thermocouple emf. must be taken into consideration.
2) The thermal characteristic test of thermocouple must be done and the best probe should be used.
3) The combination of hot junction and cold junction of thermocouple should not be changed for use and calibration.
4) There were few errors even if commercial ice and pure water were used for the cold bath.
5) Calibration must be done for temperature measurement by resistance temperature probe.
