High Quality TBTRMR-1J Retroreflectometer for road marking

Share to:
TBTRMR-1J Road Marking Retroreflectometer is a portable on-site measuring instrument, used for measuring the retroreflection characteristic of road marking. This 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 in daytime, namely, RL & QD value.
