Abstract

Much higher metrological characteristics, in comparison with known solutions, of proposed two-colour compensating thermometry method of metal alloys with randomly variable selectivity of radiation were determined. Methodical errors of two-colour compensating thermometry are lower than errors of energy one-colour and spectral ratio pyrometry in 4,4...6,2 and 40,2 times, respectively.
