Road Marking Retroreflectometer with QD & RL Value Manufacturer

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 daytime & night, and the measured parameter is the coefficient of retroreflection brightness at daytime & night, namely, QD & RL value.

Feature:

1. Equip with imported sensor

2. 5” LCD touch screen

3. Long battery time and adapting to fast charging

4. Real on site temp. & humidity displayed

5. USB interface, easy transfer the testing data to computer

6. Real time broadcasting of testing data

7. Bluetooth printer

8. GPS function
