Aeroqual AQS 1

Aeroqual AQS 1


Aeroqual’s AQS 1 is a lightweight, near reference ambient air quality analyzer that measures particulate matter and up to three gases simultaneously. PM 2.5 and PM 10 sensors allow your organization to comply with wildfire ash monitoring regulations such as: Cal/OSHA Title 8, Section 5141.1, Oregon’s EO 20-04, and Washington’s WAC 296-62-085 and fire clean-up activities.

The AQS 1 is designed for both short- and long-term monitoring studies, equipped with state-of-the-art, cloud-based real-time monitoring software and affordable enough to be deployed in small networks for many types of applications, including: fenceline site contribution, urban air quality studies, construction site pollution and dust monitoring, fire remediation, Brownfield analyses, and more.

The modular AQS-1 system can be customized with only the sensor modules you need today and is adaptable and upgradable for tomorrow. With swappable sensors, users can measure the following parameters:

Particulate matter: TSP, PM10, PM2.5, PM1

Gases: O3, NO2, VOC, CO

Environmental: Temperature, Humidity, Precipitation, Air Pressure, Wind Speed and Direction, Solar Radiation, and Noise
