Handheld Infrared Methane Gas Detector JHB Series - 2

Working principle  CH4 gas is composed of different types of atoms have absorption spectrum in infrared range. Absorption intensity abides by Lamber-Beer’s Law. Basic working principle of NDIR sensor is as below, Inlet detector Light spectral filter  Basic mathematical model ： A majority of both organic and inorganic polyatomic gas have specific absorptive wavelength in infrared region. It observes Lambert-Beer Law formula I ＝ I0e-kpl when infrared light is coming through. Light absorption intensity “i” can be described as i=I0-I= I0 (1- e- kpl). I0: intensity of incoming ray. I:...
