Product Information
Carbon dioxide is a greenhouse gas measured in ambient air quality and environmental research. The Aeroqual CO₂ module adds continuous concentration measurements to an AQM 65 system, supporting the assessment of local patterns and changes over time.
Product Features

The module is intended for indicative ambient CO₂ monitoring.
Performance & Field Data
NDIR sensing provides selective CO₂ measurement, and the module can be field calibrated using reference gases. For ambient studies, assess results against a representative site baseline. Concentration measurements alone should not be presented as a measurement of total emissions.
Performance depends on the monitoring configuration, calibration, site conditions and measurement objectives.
Typical Applications
- Ambient CO₂ trend monitoring
- Greenhouse gas research
- Environmental impact assessments
