Thermocouple inhomogeneity is one of the major factors that influence the accuracy of temperature measurement. This paper made a brief summary of the research status on thermocouple inhomogeneity and the working principle, structure and the merits and demerits of the different kinds of test equippments used in different temperature range.A set of test trig used in the cryogenic conditions was also designed and manufactured. There should have more detailed and thorough research on the thermocouple inhomogeneity,to enlight all the factors that influence the improvement of the thermometry accurarcy through the whole life cycle of thermocouples,and to establish the quality control system for the thermocouples.
