A complete ambient air monitoring station for a wide range of particulate and gaseous pollutants and environmental conditions.

The AQM’s sensor-based analyzer modules are a unique hybrid between sensors and analyzers, with a system designed to be calibrated in situ using Standard Reference Materials for best practice.

With advanced temperature and humidity control, the AQM has proven long term performance in extreme climates.



AQM 65 Ambient Air Monitoring Station

The AQM 65 can measure up to 20 different gaseous and particulate pollutants and environmental parameters simultaneously and in real-time. Data is defensible to US EPA and EU standards.

AQM 65 Air Monitoring Station with Integrated Calibration

The AQM 65 is available with a fully integrated calibration system which enables automatic scheduling of calibrations – reducing the cost of servicing and ideal for remote access sites.

The AQM 65 system is modular, with each sensor housed in an analyzer module. You choose the parameters you wish to measure.

This unique hybrid design between sensors and analyzers makes any combination possible and means you can add parameters in the future. Each module is connected with the control system for air sampling, data and power.

We integrate and test the analyzer modules and environmental sensors here at our factory and ship the fully integrated system to you for installation and commissioning.

The AQM 65 can be customized to measure up to 20 different gaseous and particulate pollutants and environmental parameters simultaneously.

AQM 65 sensor-based analyzer modules

Sensor-based analyzer modules

The AQM 65 system uses sensor-based analyzer modules, which are a unique hybrid of sensor and analyzer technology. Modules incorporate physical scrubbers and a switching sampling circuit to remove interfering gases, minimize temperature humidity effects, and provide a true zero calibration.

AQM 65 portable and integrated calibration options

Calibration to standard materials

The AQM 65 is designed to be calibrated in situ using Standard Reference Materials, the same way a government reference monitoring station is calibrated. This gives maximum confidence in the data. Portable and integrated calibration options are available.

AQM 65 temperature and humidity control to perform in extreme climates

Temperature and humidity control

An integrated Thermal Management System maintains the AQM 65 at a constant temperature +/-0.2 degree C. We combine this with an IP65 rated weatherproof enclosure, solar reflective outer layer and internal insulation, keeping the internal environment stable for optimal performance in tropical to sub-arctic climates.


Air monitoring software

The Aeroqual Cloud software is accessed via browser on your phone, tablet or PC. You can see all your data in one place and set alerts on parameters of concern. It also allows users to view where your monitors are located on a map, average data, plot charts and manage the instrument remotely.

Flexible communications

A flexible communications platform transfers your real-time data wirelessly, via WIFI, cellular modem, or local API. The AQM 65 system has on-board storage capacity to minimize risk of data loss, and data can be downloaded directly from the instrument if required.

Remote diagnostics and support

Communication with your instrument is 2-way and data is collected in real-time, so it’s easy to identify the operational status of the system. An optional remote technical support service maximizes the useful life of the sensors while keeping high quality data flowing.

Leading class technology

Advanced sensor-based analyzer modules allow the AQM 65 to measure ambient air with Near Reference data quality. Take a closer look at all the AQM 65 tech: AQM 65 Infographic.

AQM 65 system: How does it work?


In head-to-head field trials the AQM 65 demonstrates strong statistical correlation to U.S. EPA and EU approved reference analyzers. Recent colocation field studies in the USA and Australia compared data recorded on the AQM 65 with EPA reference stations.

Connecticut, USA colocation field study

An AQM 65 was installed at the Connecticut Department of Energy and Environmental Protection (DEEP) air monitoring site for four months. The AQM 65 was compared against the EPA reference air quality analyzers from December 2016 to April 2017. Overall the results indicate a high degree of correlation and low rates of long term drift for all measurements. In summary:

  • Ozone (O3) showed excellent correlation: R2 = 0.93
  • Nitrogen dioxide (NO2) showed good correlation: R2 = 0.87
  • Particulate matter (PM2.5) showed excellent correlation: FEM R2 = 0.92; FRM R2 = 0.94
  • Data capture rate of 99% exceeded the capture rates of the reference station measurements.

New South Wales, Australia OEH colocation field study

An AQM 65 was installed at the New South Wales Office of Environment and Heritage (NSW OEH) Chullora reference air quality station for four months. The study evaluated the AQM 65 data correlation with local reference air quality data from November 2015 to February 2016. Overall the AQM 65 performed reliably and accurately. In summary:

  • Ozone (O3) showed high correlation: R2 = 0.98
  • Nitrogen dioxide (NO2) showed high correlation: R2 = 0.82
  • Carbon monoxide (CO) showed high correlation: R2 = 0.86
  • PM2.5 showed high correlation: R2 = 0.86
  • PM10 showed high correlation: R2 = 0.80
  • Recorded 90% data validity for hourly data, and >95% for daily data
  • Demonstrated excellent response to ambient conditions, including very good ability to measure relatively low ambient concentrations.
