Aeroqual AQS1 Air Quality Monitor

Product Information

The Aeroqual AQS1 is a perimeter air quality monitor designed to measure particulate matter and up to 4 gaseous pollutants. Measures and reports data in 1-minute intervals with user selectable averaging, delivering highly accurate results with very strong correlation to US EPA reference analyzers. 

Suitable for use on a range of projects, including site remediation and clean-up, construction, urban and national air monitoring networks, community exposure studies, compliance monitoring, fenceline and fugitive emissions monitoring, environmental impact assessments, and industrial hygiene.
