Extractive measurement of visibility

The VICOTEC450 visibility measurement system can be mounted outside the tunnel, which makes access possible during operation. The VICOTEC450 is extremely rugged and is immune to external influences such as fog, contamination and small animals. The measured values are used for accurate, reliable control of the tunnel ventilation.
