The AQS 1 is a compact ‘smog monitor’ designed to measure the key ingredients of photochemical smog – PM2.5 and ozone (O3). 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.

Air quality professionals and researchers use the AQS 1 smog monitor to better understand the spatial and temporal distribution of ozone and PM2.5 which are two of the most important pollutants. PM2.5 is often the most damaging pollutant during winter; ozone is often the most harmful during summer. They are also key contributors to photochemical smog. To learn more about these important pollutants read this article.

Industry-leading technology

The AQS 1 combines a robust nephelometer, PM2.5 sharp cut cyclone, and Aeroqual’s industry leading GSS ozone sensor technology. The monitor performs to Near Reference levels yet costs much less than comparable analyzers; it is also lightweight and can be installed and moved with ease.

The AQS 1 is a fully integrated monitor. 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 PM2.5 for example, and add ozone 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.

Global distributors

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.

Air quality monitoring software

Once the instrument operating system is installed, Aeroqual Connect lets you access data, assess performance and diagnose faults remotely (if you choose to give us access, we can help with that too). Aeroqual Cloud offers even greater levels of convenience with enhanced browsing speeds, multiple user management, fail-safe backup, email and SMS alerts and access to your data even when your instrument is offline.

Servicing

Keep calibration up to date without the downtime. Maintaining an up-to-date calibration certificate gives you and project stakeholders confidence in the data from the air monitoring instruments. Our Hot-swap Service makes the process of factory calibration easy. We send you a freshly calibrated module from our stock. You replace the old module with the new one and send the old one back to us. And that’s it – calibration all up to date and zero downtime.
