It has been shown that the method of color pyrometry, known as the spectral ratio method, should be used to determine the temperature of an object. The main advantage of this method is the independence of the measured temperature from the coefficient of radiative capacity of the body surface. For the practical implementation of the process of measuring the temperature in a high-temperature chamber for the purification of natural graphite, modernized and adapted small-sized spectrophotometer S100 based on the CCD line TCD 1304 AP, manufactured by Toshiba. A special lens coupled with optical fiber has been developed and manufactured. A method for calculating the calibration curves of a spectrophotometer using the Mathcad package has been developed. The spectra of thermal radiation from the working chamber of a high-temperature installation with an electrothermal fluidized bed are obtained.  The results can be used in energy obtaining, by obtaining high-tech materials, by research.
