This product adopts the gas filter correlation infrared method. Through the periodic rapid rotation of the filter correlation wheel, the dark background signal, sample gas spectrum signal and reference signal are collected cyclically and rapidly to obtain the absorption signal value of CO, and the corresponding concentration is obtained according to the Lambert-Beer law.
All core components are self-developed, the optical path system is optimized, the optical path of the gas chamber reaches 16 meters, and the detection limit is as low as 0.02ppm.
Modular design, convenient operation and maintenance, comprehensive startup self-test and operation self-diagnosis functions, convenient for users to quickly locate and judge faults.
It can be applied to air quality monitoring, emission source monitoring, air component stations and roadside stations, emission monitoring in industrial parks, and navigation investigation.
