Enabled with 5.7” high-resolution colour touchscreen, The retroreflectometer offers an excellent visibility under all light conditions.

The handheld retro reflectometer offers Ultrafast retroreflection measurement (RL and Qd) in about 2 seconds for all types of road & pavement markings with a touch of button. 


The Portable Zhentner Retroreflectometer is highly efficient in measurement, can be used in any weather condition; dry or wet, day or night, on the road or in the laboratory.



Road Marking ensure road safety by directing & guiding drivers on the road Reflective road markings which are embedded with an optimal level of glass beads for ensuring retro-reflection from the vehicles headlights.


The reflectance from the road markings degrade over time and should be periodically measured, preferable every 2 years for ensuring drivers safety.



A retro reflectometer is used to measure the retro reflection performance of the surface. The ability of a driver to view the markings, while driving at speed, from a distance, whether in day or night, dry or wet, can ensure avoidance of accidents.
