The marking retroreflectometer is a portable on-site measuring instrument, used for measuring the retroreflection characteristic of road marking. On the one hand,the 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. On the other hand, the instrument is to simulate the visibility of road markings under daylight conditions. The measured parameter is daylight visibility, namely, QD value.
Designed with high precision and high stability structure, The marking retroreflectometer applies high-standard MCU master module, large-capacity storage unit, touch screen display with handwriting input function and embedded program control software, supports for rapid inspection . It is featured by free preheating, small measurement error, out-of-the-box and so on. This is a necessary instrument for the production, quality supervision, engineering construction, supervision and other units to measure the retroreflection performance of road marking.

Working Principle
The geometric condition of the marking retroreflectometer is to simulate the brightness that the driver observes in the cab reflected from the marking made of retroreflective material on the road by the headlamp when the vehicle is driven on the road at night. The schematic diagram of the optical path is shown in Fig. 2.
