JX-CO2-103 series is a kind of sensor that uses non-dispersive infrared technology (NDIR) to measure carbon dioxide. The products are divided into pump suction type and diffusion type. After the infrared radiation emitted by the infrared light source is absorbed by the gas to be measured at a certain concentration, the spectral intensity proportional to the gas concentration will change, so the variation of the spectral intensity can be obtained to reverse the concentration of the gas to be measured. The infrared carbon dioxide sensor module adopts the NDIR infrared absorption detection principle, combines the advanced optical path, the precision circuit and the intelligent software, forms a CO2 sensor module. This product adopts imported infrared light source and double channel thermoelectric reactor detector, which has excellent temperature compensation for measurement and reference signal processing. Even under bad temperature and environmental conditions, stable and reliable measurement results can be obtained. Has NDIR product unique good selectivity, high sensitivity, no oxygen dependence, long life and other
3 characteristics. JX-CO2-103 series of products are made of aluminum alloy polishing process. The pump suction module can be widely used in medical petri dish, air detection and chemical gas production process monitoring, and the diffusion module is suitable for measuring gas leakage environment. The module can be installed in intelligent buildings, ventilation systems, controllers, robots, cars and other applications.
