Airport Monitoring

Airport Monitoring 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.
The Opsis systems have been approved by the German TÜV and the U.S. EPA among others.

Several gas parameters can be monitored, among others:

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

     

                                                                                                                                                                                                  

 

           Major benefits

  • Total monitoring solution 
  • Cost-effective, open-path technology
  • High-performance monitoring of criteria pollutants

EnviMan Data Management Systems

We offer complete software packages for data handling the 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.

 

AQM Stations

AQM stations, used for street-level, urban trend and background applications are available.The monitoring systems have been approved by the German TÜV and the U.S. EPA among others.

Several gas parameters can be monitored

  •     Nitrogen dioxide NO2, sulphur dioxide SO2, ozone O3
  •     Benzene, toluene, formaldehyde, 1,2,4-trimethylbenzene
  •     Dust – PM10, PM2.5, TSP
  •     Mercury

 The EnviMan software for air quality management provides

  •     Automatic data acquisition, validation and reporting
  •     Data loggers
  •     GIS modules
  •     Forecasting

Fence-Line Monitoring of Fugitive Emissions

The Opsis open-path monitoring system is an excellent tool for monitoring air quality, fugitive emissions and gas leaks at industrial sites. By arranging monitoring paths strategically at locations outside the borderline of an industrial area, fugitive emissions and gas leaks will effectively be detected. By combining the measured gas data with meteorological parameters information such as where the pollution sources are located and the strength of the emissions can be calculated, using the EnviMan software.

Gas Parameters

The Gas Parameters system can monitor a majority of the gas pollutants that would be of interest for an industrial fence line application. Gas parameters such as nitrogen dioxide, sulphur dioxide and ozone can be monitored together with specific aromatic compounds such as benzene, toluene, and xylenes, and smelling compounds such as ammonia, styrene and phenol. Many more gases can be found in the List of Gas Parameters.
