Retroreflection, also called night visibility, is a specific type of light reflection when the light rays goes on a surface and comes back to the source of light. This principle is a pillar in road safety. Indeed, the vehicles lamps during the night enable to see the road markings, road signs and conspicuity tapes. A retroreflectometer is used to measure the retroreflection performance of the surface. The retroreflection (often written “Râ€) is measured in mcd. m-2. lx-1.
Day visibility is the luminance coefficient under diffuse illumination (from the sun or urban lightning). This principle is important in road safety. Vehicles drivers must be able to see the road markings and signs . A retroreflectometer is used to measure the day visibility performance of the surface. The day visibility (written “Qdâ€) is measured in mcd. m-2. lx-1
The Zehntner ZRM 6014 RL-Qd is an advanced retroreflectometer designed for measuring the retroreflection and daytime visibility of road markings under dry and wet conditions.
The device measures RL (nighttime retroreflection) and Qd (daytime luminance coefficient) for evaluating road marking visibility and safety performance.
The RL measurement range is up to approximately 4000 mcd/m²/lx, enabling highly accurate retroreflection testing of road markings.
The Qd measurement range is up to approximately 318 mcd/m²/lx, suitable for evaluating daytime road marking visibility.
RL ensures visibility during nighttime driving under vehicle headlights, while Qd evaluates visibility during daytime conditions, improving overall traffic safety.
Yes, the ZRM 6014 supports wet retroreflection measurement for evaluating road marking performance during rainy and wet road conditions.
The device complies with major international standards including EN 1436 (RL/Qd), ASTM E1710 (RL), ASTM E2302 (Qd), ASTM E2177 (RL wet / nass)
Yes, integrated GPS functionality enables georeferenced measurement recording and location tracking of inspection points.
GPS tagging allows accurate location documentation, route tracking, maintenance planning, and GIS integration for roadway asset management.
The ZRM 6014 features a high-resolution color touchscreen display for clear visualization of RL, Qd, GPS, and measurement data.
Yes, the intuitive touchscreen interface simplifies operation and speeds up road marking inspection workflows.
Yes, the device includes internal memory for storing measurement records, inspection history, and test results.
Yes, measurement data can be exported via USB and digital communication interfaces for reporting and analysis.
The device supports USB and digital communication interfaces for seamless data transfer and software integration.
Yes, it is widely used for highways, municipal roads, airports, pedestrian crossings, and industrial traffic markings.
Yes, the device is suitable for testing airport runway and taxiway marking visibility and retroreflection performance.
