Retroreflectometer for Road Marking with RL & Qd Value
Introduction
TBTRMR-1JS adopts compact size design for enhanced portability, it is used to determine the retroreflective properties by simulating the process in which vehicle headlamps illuminate the road/airport markings and then reflect light back to the driver.
It supports the comprehensive measurement of daytime visibility (Qd), nighttime visibility (RL) and RL under standard conditions of wetness.
Features
1. Equipped with an imported sensor to ensure measurement accuracy;
2. Color touch screen for real-time information display;
3. Average calculation & data assessment for measurement results;
4. Real-time voice broadcast for test data;
5. Bluetooth printer, USB port for exporting test data to PC and displaying measurements on Google Earth;
6. GPS(longitude & latitude), level meter(across & along) and compass(heading) for each test;
7. Equipped with front & bottom cameras for specimen status record;
8. Night-time chromaticity(optional function);
9. Multi-language interface available.
