Ambient air quality monitoring is the systematic, long-term assessment of pollutant levels by measuring the concentration and types of certain pollutants in the surrounding, outdoor air. Some of these pollutants (commonly called ‘Criteria Pollutants’) are considered hazardous to human health and their levels are regulated by government agencies around the world, including the US EPA. 

​Teledyne API provides a complete line of ambient air quality monitoring instruments, including those for both gas and particulate pollution, as well as calibration instruments that help ensure consistently high data quality to government agencies, consultants, industrial facilities, and institut​​​​​ions around the world.​
