In this work, experimental measurements of temperatures within the thermal radiation spectrum of objects with unknown radiating abilities in the wide range of temperatures (from 250 to 10000 K) are performed. The parameters of spectrometers are defined by measuring temperatures within the ranges of1000-5000 K and 5000-10000 K.
