Introduction to the measurement principle:
◆ Infrared gas detection principleNon-dispersive
infrared spectroscopic gas concentration detection technologyNon-spectroscopic
infrared (NDIR) sensor is mostly used in the field of gas analysis as a means of spectral detection. It is mainly composed of infrared light source, air chamber, wavelength filter and infrared detector. The gas is introduced into the gas chamber by pumping, and the gas concentration is detected by electro-optical modulation relationship according to the absorption characteristics corresponding to the infrared spectrum of the gas at a specific wavelength.
