Infrared gas sensor based on non-dispersive infrared (NDIR) principle, compared with the traditional principle of gas sensor has good stability, wide detection range, strong selectivity, no oxygen dependence, strong anti-interference ability, long life, long maintenance cycle and other advantages, is the development trend of gas detection, can quickly replace the traditional principle of gas sensor. Widely used in the presence of methane and explosive gas.
Field of Application：Petroleum, chemical industry, mining, environmental monitoring, biogas concentration measurement, municipal pipe network gas and gasoline leakage
