Retroreflective Performance Measurement For Road Markings Retroreflectometer With Large Data Storage
Retroreflective Performance Measurement for Road Markings Retroreflectometer with Large Data Storage
Retroreflectometer for road markings is used to measure the brightness coefficient of line retroreflection. The main characteristic of its research is to simulate the brightness of the markings on the road surface when a motor vehicle is driving at night. After being reflected by the headlights, the brightness is observed by the driver in the cab, the measured parameter is the nighttime retroreflection brightness coefficient, which is the rl value. This instrument is easy to operate and has reliable measurement values. It is suitable for both laboratory environments and outdoor on-site measurements. It is a necessary instrument for production, quality supervision, engineering construction, supervision and other units to measure the retroreflecitve performance of road markings.
