Pavement Marking Retroreflectometer RL&QD Retroreflectance measuring instrument
PRoduct description
AT-RMQD-001 Retroreflectance measuring instrument is a portable field measuring instrument, which can simulate the road marking brightness visible to the driver under the headlamp illumination of motor vehicle at night. The measured parameter is the luminous Retroreflectance coefficient at night, i.e. RL value, in mcd·m-2·lx-1. It is used to measure the retroreflection characteristics of road markings. The Reflectivity Tester is suitable for laboratory environment and field measurement. Road marking manufacturers, road marking process construction units and road quality supervision units are used to measure the retroreflective performance of road markings.
