Aeroqual AQS 1 Urban Air Quality Monitor

Aeroqual AQS 1 Urban Air Quality Monitor

Pine Item #
The AQS 1 is a compact ambient air quality monitor that targets specific pollutants in the urban environment. It can be configured to measure nitrogen dioxide, ozone and particulate matter, which are the most commonly measured pollutants in the urban environment.

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 enable networks of greater density. By using this tool air quality professionals can gain new insight into pollutant activity in the micro-environment.

The AQS 1 combines a robust nephelometer, sharp cut cyclone, and Aeroqual’s industry-leading GSS ozone sensor technology. It uses a patented method to correct for ozone interference on the electrochemical NO2, a well-known issue with all electrochemical NO2 sensors. In so doing, the monitor performs to Near Reference levels, producing data of a superior quality to other sensor-based instruments.

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.

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).

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.

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.
