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.
