Street-level Monitoring

To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate.

The OPSIS open-path monitoring systems provide a flexible solution, giving the average concentration for an area. A single OPSIS system can measure all relevant gaseous components set by the authorities, such as NO, NO2, SO2, O3, BTX, NH3.

    OPSIS Open-Path DOAS

    • OPSIS Open-Path DOAS

    The air we breathe affects our health, and the air must be monitored. We need to know how vehicle emissions and industries impact the air quality around us. 

    With OPSIS open-path DOAS, the air quality can be monitored very reliably. The OPSIS DOAS system processes the measurements digitally and is built on state-of-the-art technology. It utilizes a beam of light to probe the air. There are no pumps or filters that need to be serviced frequently.  

    Only one analyser is needed to measure all relevant gases. The system is leaner and more reliable. The service related costs will decrease when installing an OPSIS system, and the availability of data is high.

    Real Driving Emissions

    • Real Driving Emissions

    The emissions from fossil fuel cars are too high, and previous test methods have not given the full picture. Laboratory tests do not show the real driving conditions. Now, there is monitoring equipment that can easily monitor emissions from fossil fuel vehicles in an accurate way, by monitoring real driving emissions. 

    OPSIS offers measurement of car emissions with our latest invention - the RD100 Real Driving Emissions monitoring system. This system, installed directly on the vehicle, measures emissions in real time. Watch the video and find out how.
