Infrared nitric oxide sensor is a sensor that uses non-dispersive infrared technology (NDIR) to measure nitric oxide. Products are divided into pump suction and diffusion. The infrared radiation emitted by the infrared light source is absorbed by the gas to be measured with a certain concentration. The spectral intensity changes proportional to the gas concentration. Therefore, the concentration of the gas to be measured can be inverted by obtaining the variation of the spectral light intensity. The infrared nitric oxide sensor module adopts the NDIR infrared absorption detection principle. Combining advanced optical paths, precision circuits and intelligent software. A universal infrared NO sensor module is formed.
