FIELD: measurement technology. SUBSTANCE: device may be used in direction spheres of production for measuring of high temperatures. Device has main and compensation thermocouples 1, compensation bridge 2, first and second interference suppression devices 3, 4 first and second adders 5, 6, first voltage divider with controllable division factor second controllable bias-voltage divider 8, unit of single-threshold level comparators 9, matching device 10, and recorder 11. Construction of device provided for simulation of calibration curve of main thermocouple in the form of linear-sectional curve by calibration curve of compensation thermocouple. EFFECT: higher reliability and accuracy of temperature measurement due to reduced number of active elements in device. 5 dwg
