Measures and reports data in 1-minute intervals with user selectable averaging

Robust, weatherproof enclosure with solar shielding, suitable for use in most conditions

Product overview

The AQS 1 Urban Air Quality Monitor is a compact ambient air quality monitor that targets specific pollutants in the urban environment. It can be configured to measure the most common pollutants in the urban environment – nitrogen dioxide (NO2), ozone (O3), and particulate matter (TSP, PM10 and PM2.5), with the option to measure volatile organic compounds (VOCs) via an upgrade, if required.

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. At the same time its small size and lower price enables networks of greater density. By using this tool air quality professionals can gain new insight to pollutant activity in the micro-environment.

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, PM2.5, PM1) and up to three gases (O3, NO2, VOCs) 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).

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 an Optical Particle Counter (Profiler). The Profiler can measure PM1, PM2.5, PM10, and total PM simultaneously.

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:

  1. Factory calibration pre-shipment is standard on all our instruments.

  2. 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.

  3. 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:

  1. AQS Particle Monitor: 24 Months

  2. 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)

  • Met One MSO (weather transmitter)

  • 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.

What are the available outputs?

  • 2 x Relay (optional)

  • 4 x 4-20 mA (optional)
