Invasive precise point measurement of the road condition

Invasive sensors embedded in the road allows all time measurements of water film height, road surface and depth temperature and road condition even at heavy traffic conditions.

Maintenance, calibration and replaceability

Sensor consists of two parts: replaceable sensor head with electronics and fixed mounted socket.

Power consumption

Low energy consumption allows solar operation.

Invasive technology allows

Permanent usage on runways where non-invasive sensors cannot be used.
