Calibration of temperature control units and radiation thermometers is performed in a temperature range from - 30 to + 80 ° C according to the method of calibration of temperature control units. The methos uses the model of blackbody emitter "Demetra" that has a certificate of Conformity RF RU.C.32.001.A № 32527. Traceability of measurements to the national standard state of Russian Federation located in "Mendeleev's VNIIM", St. Petersburg is provided.
