The GW-2080 Environmental Air Greenhouse Gas Continuous Monitoring System is a greenhouse gas detection solution developed by Daren Technology based on infrared correlation wheel filtering (GFC) combined with long path gas absorption cell (L-Cell) technology. This product is a customized small-scale monitoring system developed based on the design requirements of air quality monitoring micro stations. It can achieve real-time and accurate online monitoring of greenhouse gases such as CO2, N2O, CH4, as well as meteorological parameters such as wind direction, wind speed, temperature and humidity, and air pressure in the atmosphere.

GW-2080Continuous monitoring system for greenhouse gases in ambient airTechnical principle:
The infrared light emitted by the light source alternately enters the gas pool through the GFC modulation wheel. One path is absorbed by bubbles filled with the gas to be measured, and the other path passes through bubbles without the gas to be measured. The two paths of light are converged by lenses and received by infrared detectors. After signal processing, the measurement signal and reference signal are obtained. By analyzing the two signals, the concentration of relevant components in the gas can be obtained.
