The AQS Series is designed for short and long-term air quality monitoring studies. It comes equipped with cutting-edge air monitoring software and is affordable enough to be deployed in small networks for a range of outdoor applications. Measures and reports data in 1-minute intervals with user-selectable averaging, delivering highly accurate results with excellent correlation to US EPA reference analyzers. Designed to be calibrated in situ using reference materials, ensuring data is traceable back to international standards.
Features a modular design, which can be upgraded at any time to measure additional parameters as needed. All module data is available to view through our air monitoring software, Aeroqual Cloud. Choose from several parameters.
Key technology of the AQS Series
Pumped Sampling System
Provides a steady flow of air to the sensor modules as filters help protect sensors from airborne impurities, extending the instrument’s operating life.
Automatic Baseline Correction (ABC)
Pioneered by Aeroqual, ABC sees the automatic correction of the ‘zero”baseline every 60 seconds. Corrects for cross interferences and sensor drift – two of the biggest problems for sensor-based monitors
The NO2 module design incoporates an electrochemical sensor with Aeroqual’s Automatic Baseline Correction (ABC) Technology, maintaining measurement stability. An intergrated O3 filter guards against interference, so you know exactly how much NO2 is present.
Robust PM Sensing
The integrated nephelometer is proven to last years in the field and is coupled with a pumped sampling system and inlet heater to correct for humidity interference.
Factory And Field Calibration
The AQS Series is field calibrated using the same reference materials as a U.6 EPA / EU-Certified analyzer. Sensor modules are calibrated against high-purity gas standards prepared under ISO 6143, ensuring traceability to reference materials from National Metrology Institutes
