IRIMETER-2 Vehicle Mounted IRI Measurement System

Englo's IRIMETER-2 is a vehicle-mounted IRI measuring device designed for continuous, reliable measurement of road surface roughness in terms of the International Roughness Index (IRI). Installed on a standard vehicle, IRIMETER-2 enables fast network-level surveys while driving at normal traffic speeds, making it an efficient solution for large-scale pavement condition assessment.

Compact, robust, and easy to operate, IRIMETER-2 is ideal for road authorities, municipalities, consultants, and pavement management professionals.

Features and Benefits

Continuous IRI Measurement at Traffic Speed

• Measures International Roughness Index (IRI) continuously along the road

• Suitable for surveys at normal driving speeds
