The CO module is a continuous sensor-based carbon monoxide 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 and AQS mini air quality station.

The carbon monoxide 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 and maintaining the AQM 65 enclosure at a constant temperature.

Just like a traditional analyzer using NDIR gas filter correlation, this sensor-based CO 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 NDIR gas filter correlation the CO module is compact, lightweight and costs 5 x less to own and operate.

Typical applications include:

  • urban and national ambient air quality monitoring
  • power station perimeter monitoring
  • near roadside monitoring
  • checking pollution ‘hotspots’
  • air quality research
  • environmental impact assessments (EIA)
