The AQS is a tool for air quality professionals to target specific applications of interest in the urban environment. It is a flexible air quality monitoring system that can be configured for a range of uses.The monitor performs to Near Reference levels yet costs much less than comparable analysers. The unit is also lightweight and can be installed and moved with ease.
What does AQS measure?
The Aeroqual AQS can measure particulate matter (PM) and up to two gases at the same time. You can choose from the following parameters.
  • Particulate matter (TSP, PM10, PM2.5, PM1)
  • Gases: Ozone, Nitrogen dioxide, VOCs
  • Meteorological (temp, humidity, rain, pressure, wind speed / direction, solar radiation)
  • Noise
At any time the Aeroqual AQS can be upgraded to measure additional parameters by adding new modules. New modules can be added in the field; there is no need to return the unit to the factory.

How is AQS different?
Collectively the key features of the AQS enable it to deliver near reference data quality over extended periods of time – several years with appropriate maintenance. In head to head tests with traditional EPA-approved analysers, the Aeroqual AQS has shown r2 correlations as high as 0.98. The AQS produces better data for longer periods because Aeroqual’s ABC methodology eliminates diurnal and seasonal temperature and humidity effects which affect other sensor-based instruments. The computational method is patented and proprietary to Aeroqual.
