The SO2 module is a continuous sensor-based sulfur dioxide analyzer used to to detect pollutant gas in ambient air. It can also be used to detect point source emissions. The module is designed for use in the AQM 65 compact air monitoring station.
The sulfur dioxide analyzer module incorporates next generation electrochemical cells with nano-catalyst coated working electrodes that provide higher sensitivities. The lowest possible detection limits are achieved by proprietary signal processing, adding a zero cycle scrubber, and maintaining the AQM 65 enclosure at a constant temperature.
Just like a traditional analyzer using UV fluorescence, this sensor-based SO2 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 using UV fluorescence the SO2 module is compact, lightweight and costs 5 x less to own and operate.
Typical applications include:
- urban and national ambient air quality monitoring
- oil and gas facility perimeter monitoring
- coal fired power station perimeter monitoring
- near roadside monitoring
- checking pollution ‘hotspots’
- air quality research
- environmental impact assessments (EIA)
