Road Marking Retroreflectometer Equip with QD Value Function

Road Marking Retroreflectometer is a portable on-site measuring instrument that is used for measuring the retroreflection characteristic of road marking, the weight is 5kg.
The purpose of this road marking instrument is to simulate the brightness of road markings that can be seen by drivers under the illumination of motor vehicles at night, and the measured parameter is the coefficient of retrorefection brightness at night in daytime, namely, RL & QD value.
