ABSTRACT:
An infrared gas detector for detecting a density of a sample gas includes an infrared light sensor for detecting the density of the sample gas under an influence of water vapor based on an intensity of received infrared light of a specific wavelength, and a humidity sensor for detecting an absolute humidity of the water vapor in the sample gas based on an intensity of the received infrared light of the specific wavelength. The density of the sample gas is determined by correcting for the influence of the water vapor included therein based on the absolute humidity in the sample gas detected by the humidity sensor.
