The new technique for estimating gas temperature at more than 1000°C was developed based on quantum mechanics. The spectrum of gas at the fixed temperature in the experimental furnace was observed. Carbon monoxide was chosen as a "probe" gas for the examination. The gas was monitored by an infrared optical sensor with Fourier Transform Infrared Spectrometer ( FTIR ). Zinc selenide lens and KRS-5 infrared optical fiber were set in a water cooled probe. The shape of the P-branch in vibrationalrotational spectrum of carbon monoxide was examined as an index for temperature and partial pressure. The evaluation of temperature ranging from 1000 to 1550°C was possible by using the shape analysis of spectrum at PCO = 0.31.0 atm.
