IRIMETER-1 vehicle-mounted road roughness measuring device measures the International Roughness Index (IRI) of different road surfaces.

​

This vehicle mounted profilometers includes a control unit with graphic LCD display, one or two wireless inertial sensors, induction sensor for distance measurement and a roof magnet-mounted GPS antenna. The inertial sensors are mounted to MacPherson type front suspension of the vehicle. Cables are used to connect the sensors to the rest of the system.

​

IRIMETER-1 can be used on paved or unpaved roads. Wet, snowy or dusty road surface do not influence the accuracy of measurement.

​

All measured data together with measurement location is stored and can be downloaded to a computer via USB connection and can be viewed as graphs, tables and maps. Software is provided for easy processing and display of the data.
