                             Scanning Infrared Gas Imaging System
                             Remote Monitoring of Hazardous Gases

SIGIS2   New generation Stand Off Gas Identification and Imaging System
         Designed for Public Safety, First Response and Environment

    The SIGIS2 (Scanning Infrared Gas                    Monitoring Public Events
    Imaging System) provides                      During the FIFA World Cup 2006 and the
         Highly resolved Imaging                  European soccer championships (2008) the
                                                  SIGIS2 systems were in use for surveillance
         Very good Sensitivity                    of the stadiums and in public viewing areas
                                                  in different cities.
         Reliable Identification
                                                  No intentional releases of hazardous gases
    of gas clouds even at large distances.        occurred, but the systems have proven their
                                                  effectiveness by identifying and locating
    By overlaying the image of spectra from       various gases in the air (Ethanol, Ammonia,
    FTIR analysis and a video image, the          SF6, Methanol).
    SIGIS2 performs accurate measurements            Monitoring Chemical Accidents

    absence of sunlight. All members of an        Visualize the origin and distribution of

                                                  Supervise the release of chemicals from
                                                  industrial plants.

    The SIGIS2 is operated in a passive
    mode, meaning that no external light
    sources are required - the use of the
    instrument is remarkably easy.
    SIGIS2 has been developed for the
    German Analytical Task Force. It complies
    with requirements of first response action
    and also has proven its capabilities during
    continuous supervision of public events.
