Modernises measurement performance for tunnel air quality
The VISIC100SF tunnel sensor is an all-in-one solution for measuring visibility, CO, and NO concentrations. It is the only product of its kind in the world to combine the scattered light measurement principle with electrochemical cells; all in one, compact housing.
The VISIC100SF is very easy to mount, operate, and maintain. There is no need for alignment or configuration, so you can start measuring 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 attached to ensuring reliable operation and long maintenance intervals. To compensate for fog, there is an optional version available with heating. Thus, the VISIC100SF is an elegant solution that meets the desired requirements and is ideal for any tunnel application.
At a glance:
- Visibility (K value) measured according to the scattered light measurement principle
