CO Analyzer
Technical principle
The basic working principle of the carbon monoxide analyzer is the gas-free non-dispersive infrared method: the absorption of infrared light based on CO molecules is consistent with Beer-Lambert's law: I = Io e-αLc Infrared light containing a specific wavelength needs to be preferentially modulated and then passes through a high concentration of carbon monoxide chamber, a pure nitrogen gas chamber. After the infrared light passes through the high concentration of carbon monoxide, Infrared light comes into the sample chamber, and then the CO no longer absorb infrared light. The basic working principle of the carbon monoxide analyzer is the gas-free non-dispersive infrared method: the absorption of infrared light based on CO molecules is consistent with Beer-Lambert's law.
