The VICOTEC450 draws air from inside the tunnel and determines the visibility with a high level of accuracy using scattered light technology. It regularly and automatically carries out a functional test including the function of the laser and receiver as well as the contamination of the optics. Maintenance requirements for cleaning and filter exchange are automatically registered and signaled in time by the VICOTEC450 due to contamination check and measurement of the air flow rate (optional).
