A sensor for measuring sulfur dioxide using nondispersive infrared technology (NDIR). This product adopts imported MEMS infrared light source and double-channel pyroelectric detector to process the measurement and reference signal and compensate the temperature, so that stable and reliable measurement results can be obtained even under harsh temperature and environmental conditions. With NDIR products unique good selectivity, high sensitivity, no oxygen dependence, long life and other characteristics.
