​​Fenceline air quality monitoring has become an area of growing interest over the past several years. Certain industrial facility processes result in the emissions of air toxins and other air pollutants into the ambient air and surrounding communities. To mitigate these fugitive emissions, facilities will typically put control systems in place, combined with perimeter (fenceline) air monitoring to assure these safety measures are working effectively. In addition, continuous and real-time air monitoring help to alert the facility to process gas leaks, failures of their control systems, or other activities that lead to unexpected fugitive emissions. This information helps the facility to take quick action and minimize pollutant emissions to the surrounding community. In addition, government regulatory air quality agencies around the world have begun putting air monitoring policies in place that require certain industrial facilities to perform fenceline air monitoring and report their data for transparency.

​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. All of our products include advanced communications capabilities that are designed to integrate seamlessly into other external data systems, providing real-time and transparent access to any instrument data or other diagnostic parameters​.
