OPSIS’ systems for ambient air quality monitoring (AQM) set the standard for reliable and cost efficient solutions to your air quality monitoring needs. OPSIS’ systems are installed and operated in multiple application areas, including but not limited to ambient trend, fence-line, street-level and tunnel applications. OPSIS has been in this business for decades, our systems have been installed all over the world, and we know how these environments work and what the expectations are.
The systems are normally centred around OPSIS’ gas analysers utilizing open-path DOAS technology for measurement of concentrations of a wide range of gaseous compounds. Measurements are made in the open air, thereby avoiding any sampling systems with pump service and filter cleaning needs.
In addition to a gas analyser, a system usually also includes OPSIS’ particulate monitors and meteorological sensors for parameters such as wind speed, wind direction, temperature, pressure, solar radiation and precipitation; in all forming a complete system providing full and continuous surveillance of the ambient air.
The OPSIS systems for ambient air quality monitoring have a great advantage in a single gas analyser being able to measure a wide range of gaseous compounds along multiple measurement paths, providing a cost efficient solution to the monitoring needs. A further advantage is the very low maintenance requirements, minimizing operating costs. The systems also allows versatile distribution of monitoring data over the Internet, providing both real-time access to air quality information and the formation of databases allowing in-depth studies and reporting of the air we breathe. OPSIS’ software solutions facilitate access to all monitoring data.
OPSIS and its representatives keep careful track of legislation and directives applicable to ambient air quality monitoring, ensuring that the system solutions always meet the requirements set by the users and the authorities.
The OPSIS range of gas analysers and particulate monitors have been tested and approved by a number of internationally recognized institutes and authorities, such as U.S. EPA, German TÜV and British MCERTS.
No matter what your ambient air quality monitoring need is, OPSIS has the solution for you.
