The VISIC100SF tunnel sensor is an all-in-one solution for measuring visibility, CO, NO, and NO2 concentrations. The VISIC100SF is easy to mount, operate, and maintain. There is no need for alignment or parameter setting. With its IP6K9K enclosure rating, the VISIC100SF is able to withstand the harsh ambient conditions inside the tunnel, also tunnel washing operations. During the design phase, particular importance was placed on ensuring reliable operation and long maintenance intervals.
