Road Roughness Measurement / IRI Meter

IRI METER 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.

RI METER 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. The sensors of the device are rated IP67 under the international IEC 60529 standard and are waterproof. Control unit is rated IP65 and is splash and dust proof.
