This paper considers the method of self-testing of thermocouple electrodes degradation without replacement from the operation place. The equivalent operating time of a thermocouple is obtained. This time allows determining its place in conversional characteristic error dependence on drift and acquired inhomogeneity. The necessary condition enabling self-testing is constant measuring junction temperature during the procedure of self-testing.
