It is mainly applied to the online monitoring of carbon emission of flue gas components CO, CO2, flue gas parameters (temperature, pressure, flow rate, humidity, oxygen content) emitted by various fixed sources, realizing the carbon emission measurement of fixed pollution source discharge by direct measurement method, and providing data support and calibration for greenhouse gas emission reduction at enterprise level.

Principle
The system uses NDIR technology to measure CO and CO, concentrations and an electrochemi-cal method for O,. The core unit includes an infrared light source, gas chamber, detector, andoptical filters. infrared light passes through the sample gas, with absorbed energy measured bythe detector. The signal is processed through filtering and correction to determine CO and CO,con centrations.
