Pavement Marking Retroreflectometer

Marking retroreflectometer is a portable on-site measuring instrument, used for measuring the retroreflection characteristic of road marking instrument is to simulate the brightness of road marking that can be seen by the driver under the illumination of motor vehicles at night, and the measured parameter is the coefficient of retrorefection brightness at night, namely, RL value.
