AQS 1 Ambient Ozone Monitor
The AQS 1 Ambient Ozone Monitor provides continuous real-time measurement of ambient ozone in air. It measures and reports data in 1-minute intervals with user selectable averaging, delivering highly accurate results with excellent correlation to US EPA reference analyzers. Suitable for use on a range of projects, including urban and national air monitoring networks, community exposure studies, and environmental impact assessments.

Robust, weatherproof enclosure with solar shielding, suitable for use in most conditions
Product overview
The AQS 1 Ambient Ozone Monitor is a compact air monitoring station designed to measure ambient ozone (O3) continuously and in real-time. Using Aeroqual’s patented sensor technology, the AQS 1 delivers very accurate measurements at a price that is well below traditional ambient air monitoring equipment, enabling deployment at a scale large enough to map ozone across large areas.
The AQS 1 is supported by a global distribution network, meaning you’re never too far from a skilled technician ready to provide assistance and spare parts. In addition, Aeroqual’s online training system is free to all our customers, meaning you can become an expert on your AQS system before it even arrives. Housed in a rugged, lockable weatherproof enclosure, it includes an embedded PC and full software system for remote technical support, data management and analytics.
What can it measure?
The AQS 1 can be configured to measure particulate matter (TSP, PM10, PM4, PM2.5 and PM1) and up to three gases (O3, NO2, CO, H2S, SO2, VOCs, CH4) simultaneously. Because it is modular, you may order the unit with just ozone, for example, and add PM or another gas at a later date (without returning to the factory).
For specific applications, see our other pre-configured AQS 1 monitors: AQS 1 Construction, AQS 1 Remediation, AQS 1 Urban.
The AQS1 now comes with the PCX Particle Module!
More mass channels simultaneously: PM1, PM2.5, PM4, PM10, and TSP mass measured as standard, with the same level of accuracy provided by our Nephelometer engine for a single mass measurement.
MCerts certified for PM10 and PM2.5: The PCX PM10 and PM2.5 are both MCerts certified so now users can get certified results for both channels simultaneously in one unit.
Key benefits of Aeroqual products
Industry-leading sensor technology
As sensor manufacturers, we know sensors inside and out and have unparalleled expertise in optimizing performance in real-world conditions.
Powerful software platform
Leveraging deep integration with our monitoring systems, we deliver software functionality unmatched by off the shelf data acquisition systems.
Value-adding services
Using proprietary system diagnostics, we enable proactive maintenance with hassle-free services that virtually eliminate system downtime.
Who is it for?
Researchers and air quality professionals use the AQS 1 Ambient Ozone monitor to better understand the spatial and temporal distribution of ozone which is an important ‘criteria’ pollutant. Ozone formation and distribution is complex and strategies for reducing ozone must start with accurate mapping of the ozone problem.
Practical applications for the AQS 1 Ambient Ozone Monitor include:
Urban air monitoring networks
National air monitoring networks
Short term monitoring of ‘hot spots’
Environmental Impact Assessments
Community exposure studies: epidemiological studies, microenvironment, residential, schools, hospitals
In future, we will add new gas modules to the AQS 1 – to register your interest please tell us about your application.

FAQs
The main difference is that the Dust Sentry measures dust and particulate matter (PM), while the AQS can measure particulate matter and up to three gases at the same time. Both are designed for continuous real-time measurement of ambient air.
The AQS can measure particulate matter (PM) and up to three 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 (temperature, humidity, rain, pressure, wind speed/direction, solar radiation)
Noise
No, the AQS only measures ozone, nitrogen dioxide and VOCs.
Yes, the system can be configured with a PCX Particle Module. The PCX Particle Module mass measures PM1, PM2.5, PM4, PM10, and TSP as standard.
Are the gas detection levels suited for indoor measurement?
Yes. However, please note that noise is generated by the equipment when it is operating.
Is it easy to install and maintain?
Installation
The AQS can be used almost anywhere – on roofs and lamp posts, by a busy street or an offshore oil rig, in cold and hot climates, on or off-grid. The unit weighs about 12kg so installation is easy; you can get set up or re-locate in under 10 minutes.
Maintenance
This is a low maintenance air quality station and the skills required for operation is relatively low.
How do we calibrate an AQS?
Gas Calibration
There are three types of calibration of the gas module:
Factory calibration pre-shipment is standard on all our instruments.
Field calibration. Typically, only advanced users will need to field calibrate their AQS. All other users can depend upon 12 monthly factory calibration of the gas module.
Factory calibration post-shipment.
Particulate Calibration
All Aeroqual PM engines need to be returned to the Met One Instruments factory in the U.S for service and calibration at the following recommended intervals:
AQS Particle Monitor: 24 Months
AQS Particle Profiler: 12 Months
Aeroqual can arrange for this service. Contact support@aeroqual.com for further details
What is the dimension and weight of an AQS monitor?
483 H x 330 W x 187 D mm (19 H x 13 W x 7.4 D inches) includes solar shield armour and mounting brackets and it weighs <13 kg (28.6 lbs).
Is the AQS a temperature-controlled enclosure?
No. However, the enclosure is a lockable IP65 rated, glass-reinforced plastic (GRP) cabinet with integrated aluminium solar shield armour.
What is the environmental operating range?
The AQS is designed to operate in environments from -10 °C to +45 °C (14 °F to 113 °F)
Can it be solar or battery powered?
Yes. To read more, see this technical note on How to remote/solar power the Dust Monitor.
Can we integrate a third-party weather station in the AQS?
Yes, a power and data interface for designated third party sensors is included.
Here is a list of the environmental sensors that integrate with the AQS system:
Gill WindSonic (ultrasonic wind sensor)
Vaisala WXT536 (weather transmitter)
Airmar 200WX (weather station)
Cirrus MK427 Class 1 (noise sensor)
Novalynx Pyranometer (solar radiation)
What communication options are there for access to the instrument?
Standard: WIFI
Ethernet (LAN)
Optional: Cellular IP HSPA 3G modem
Are all the gas module calibrated to NIST standards?
Yes. The AQS is delivered with a NIST-traceable factory calibration.
Can the AQS measure BTEX?
No. For BTEX see our Real-Time BTEX / Benzene Monitor.
