GH-CO2 series infrared carbon dioxide gas infrared sensor is based on the non-dispersive infrared (NDIR) principle. Compared with the traditional principle gas sensor, it has the advantages of good stability, wide detection range, strong selectivity, no oxygen dependence, strong anti-interference ability, long life, long maintenance cycle, etc. It is the development trend of gas detection, and can quickly replace the traditional principle gas sensor. It is widely used in various occasions of carbon dioxide gas detection.
