Roughometer III is a response-type roughness device, complying to World Bank Class 3 requirements. Unlike other devices in this class, the Roughometer III eliminates the uncertainties associated with the vehicle (such as the vehicle’s suspension or passenger weight) by directly measuring the axle movement with a precision accelerometer

WALKING PROFILER G3 produces outputs from pavement profile, providing International Roughness Index (IRI), MPD texture (as an optional parameter) and distance.
