Mobile sensor

Flexible and representative measurements from many vehicles, no fixed installation required, and hot spots for high water film heights or icying can easily be identified.

Non-invasive measuring principle

The optical (spectroscopic) measuring principle delivers the important road surface condition parameter without the need of construction works on the road itself.

Easy and flexible installation

Simple car mounting options and flexible data communication via Bluetooth, RS485, and CAN-Bus.

Low maintenance

Long life LED technique, no moving parts and easy cleaning procedure.
