The invention relates to equipment for determination of temperature and can be used at preparation of thermo-couples for operation, mostly at high temperatures, in laboratory and industrial conditions as well. The method includes bringing of one of junctions of thermo-couple to thermal contact with sample of reference substance with known melting temperature, hearting sample of reference substance with alloy of thermocouple, measurement of thermo-electromotive force of thermo-couple at instant of melting of sample of reference substance. Sample of reference substance as a plate or wire is installed in horizontal position with ends to supports, to the middle part of the sample one places load as installed in vertical position elongated body, and instant of melting of sample of reference substance is determined by displacement of position of load from initial position. The invention provides decrease of labor expenditures for calibration of thermo-couple. |
