Opsis AB

Emissions Monitoring for Airports - Aerospace & Air Transport

Opsis systems provide high-performance monitoring of the emission activities within an airport. The rapid system allows on-line monitoring of the emissions from each aircraft at take-offs and landings, monitoring of fugitive emissions from stationary sources and differing of the airport sources from the surrounding pollution sources.

Several gaseous compounds can be monitored, among others:

  • Nitrogen oxides NOx
  • Sulphur dioxide SO2
  • Benzene
  • Toluene
  • Formaldehyde
  • 1,2,4-trimethylbenzene

Why Opsis?

  • Total monitoring solution
  • Cost-effective, open-path technology
  • High-performance monitoring of criteria pollutants
  • High-performance monitoring of BTX
  • Representative path-integrated data
  • Easily calibrated
  • Operates with a minimum of maintenance
  • International approvals


Opsis offers complete software packages for data handling. Please refer to EnviMan Data Management System. The data of airport applications provides information about the general air quality and the impact of air traffic. It is also used to provide information on the environmental impact of specific aircraft. Here, correlation with air traffic data offers information on emissions in respect of aircraft type and take-off weight. The software meets the EC regulation for reporting.
