TH-2004H Infrared Absorption Carbon Monoxide Analyzer

　　working principle:
The instrument adopts gas filtering related infrared absorption method. The basic working principle is that CO has the characteristic of absorbing infrared radiation of a specific wavelength (4.67 μ m), and the strength of its absorption is related to the concentration of CO. The detection method is as follows: infrared rays from the infrared light source sequentially pass through the CO and N2 filters in the rotating filter wheel, and then enter the light chamber through the narrowband interference filter. The infrared radiation is absorbed by the CO filter in the filtering wheel, and the CO in the sample gas cannot be absorbed again in the light chamber to form a reference light intensity. The infrared radiation is not absorbed by the N2 filter in the filtering wheel and shines on the sample gas in the light chamber. The CO in the sample gas absorbs the infrared radiation, forming a measurement light intensity that passes through the light chamber and shines on the infrared detector. Calculate the concentration of CO in the sample gas using the Lambert Beer law based on the ratio of their light intensities.
