Retroreflectometer for Road Marking
Introduction
TBTRMR-1C is a portable on-site instrument which simulate the brightness of road and airport marking that can be seen by the driver under the illumination of motor vehicles, and determine the retroreflection characteristic.
It supports simultaneously measure index of night visibility(RL), temperature and humidity efficiently.
