Retroreflectometer for Road Marking with RL & Qd Value
Application
TBTRMR-1J 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 day visibility(Qd), night visibility(RL), temperature and humidity efficiently.
Features

2. Touch screen real-time display temperature and humidity;
3. Ultrafast retroreflectometer measurement;
4. Real-time broadcasting of test data;
5. USB port for test data exporting to computer;
6. Mini Bluetooth printer;
7. GPS for longitude and latitude for each test data;
8. English, Spanish and Russian language software are available.
