Abstract
Metrological problems that arise in the measurement of the temperature of physical objects performed by means of pyrometers, where the emissivity of the particular object differs from unity and may vary as a function of wavelength, are considered. Methods of correction of spectral (CT) ratio pyrometers are analyzed. A disturbance in the traceability of pyrometers provided with components for correction to the primary standard of the unit of temperature is identified. Recommendations for establishing traceability are given.
