• Reliable vehicle measurement and classification in free-flowing and stop-and-go traffic.
• Non-contact axle counting in multi-lane traffic sites.
• ANPR, WIM and RFID transponders can also be integrated.
• Can be used in all climate zones from –40 °C to +60 °C thanks to the expanded temperature range.
• Data history of the last 50 vehicles detected in the user interface.

• Early and reliable fire detection in tunnels
• Measurement principles: Scattered light forward
• Perfect addition to temperature cables thanks to earlier and faster detection
• No need for protective measures during tunnel cleaning
• Immune to gantry fog
• Visibility (K value) measured according to the scattered light measurement principle
• IP 6K9K enclosure rating thanks to a rugged stainless-steel housing

• For the control of ventilation and for filter monitoring in road tunnels
• Measured values: Visibility (K-value), NO, NO2, NOx, CO, temperature
• Measurement principles: Differential optical absorption spectroscopy (DOAS), transmittance measurement, electrochemical cell, Resistance thermometer
• Measuring distance: 10 m
• Low maintenance requirements due to long maintenance interval (approx. 1 year)
