The CO2 module is a continuous sensor-based analyzer used to measure carbon dioxide gas in ambient air. It is primarily used to quantify greenhouse gas emissions which are linked to man-made climate change. The module is designed for use in the AQM 65 compact air monitoring station.

The carbon dioxide analyzer module incorporates near dispersive infrared receptor  (NDIR) technology. NDIR sensors are highly selective to CO2 and therefore well suited to indicative ambient monitoring of this important greenhouse gas.

Just like a traditional analyzer, this sensor-based CO2 module can be field calibrated using standard calibration equipment and gases. This ensures direct traceability to USEPA (40 CFR Part 53) and EU (2008/50/EC) certified equivalent method instruments.

In contrast to traditional analyzers, the CO2 module is compact, lightweight, and costs 5 x less to own and operate.
