Research on Calibration Method of Thermal Resistance in Laboratory

Thermal resistance is widely used in temperature measurements for its advantages. When higher measurement precision is needed or use condition is changed, thermal resistance should be calibrated again.A feasible laboratory calibration method of thermal resistance at normal temperature is presented.Experiment principle,equipment and steps of the method were described.Data analysis results show that the calibration method is relatwely reliable.
