BASIC INFO 

This Retro reflectance 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 Retro reflectance coefficient at night, i.e. RL value, in mcd·m-2·lx-1.

It is used to measure the retroreflection characteristics of road markings. It 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.
