FIELD: measurement equipment.
SUBSTANCE: invention is related to the field of pyrometry and radiometry. Method includes collection and focusing of heat radiation, extraction of N spectral ranges, conversion of radiation in each spectral range into electric signal, their amplification and digitisation, detection of the first N-1 derivative signals of central spectral range by wave length, measurement of temperature and emissive power of object by functional ratio that relates selected signal and its derivatives.
EFFECT: expanded coverage of analysed objects with increase of spectral range of emissive power measurement by measured temperature.
