This paper proposed a high temperature strain calibration system which providedconstant load and constant displacement loading methods. It provides a stable heat environment and correction mod-el for the improvement of measuring accuracy of high temperature strain gauge. The whole system is composed oftemperature control,loading and measurement parts which could imitates a thermal-mechanical coupling environ-ment in real measurement to obtain the parameters vary with temperature,time etc. On the basis of calibration sys-tem,this paper did some qualitative and quantitative research and the results showed it has a good adaptability inheat,strain and loading environment. This calibration system provides the contact measurement of high temperaturea necessary experiment basis.
