Annotations languages:

The thermodynamic temperature of the high-temperatures fixed points Co-C(1597,73 К), Pt-C(2011,44 К) and Re-C(2748 К) were measured using an imaging radiation thermometer and a blackbody and a set of filter radiometers calibrated in terms of spectral irradiance responcivity against an absolute cryogenic radiometer via a trap detector.
Keywords: thermodynamic temperature, high-temperatures fixed points, trap detector, filter radiometers, cryogenic radiometer, spectral irradiance responcivity, spectral comparator
