Product Introduction

Product Overview:

The instrument adopts the gas correlation infrared absorption method. The basic working principle is: CH4 has absorption characteristics for infrared radiation of specific wavelengths, and the absorption strength is related to the CH4 concentration. Detection method: Infrared light from the infrared light source passes sequentially through the CH4 and N2 in the rotating wheel, the filter, and then enters the optical chamber through a narrow-band interference filter. The infrared light passing through the CH4 filter in the filter wheel is absorbed and cannot absorb CH4 in the sample gas again in the optical chamber, forming the reference light intensity. The infrared light passing through the N2 filter in the filter wheel is not absorbed and shines on the sample gas in the optical chamber. The CH4 in the sample gas absorbs infrared radiation, forming the measurement light intensity that passes through the optical chamber and shines on the infrared detector. The concentration of CH4 in the sample gas is calculated using the Lambert-Beer law from the ratio of the two light intensities.
