    VISIC100SF
    Modernizes measurement performance for tunnel air quality

    The VISIC100SF tunnel sensor is an all-in-one solution for measuring visibility, CO, NO, and NO2 concentrations. It is exceptional solution that combines the scattered light measurement principle with electrochemical sensors – all in one compact housing. The VISIC100SF is easy to mount, operate, and maintain. There is no need for alignment or parameter setting – measuring starts right away. With its IP6K9K enclosure rating, not only is the VISIC100SF able to withstand the harsh ambient conditions inside the tunnel, it can also endure tunnel washing operations without any problems. During the design phase, particular importance was placed on ensuring reliable operation and long maintenance intervals. That is why there are no moving parts. To compensate for fog, there is an optional version available with heating. The VISIC100SF is a solution that meets desired requirements and is ideal for any tunnel application.
