Zehntner ZRM 6013+ RL-Qd

Professional retroreflectometer for day and night visibility.

The Zehntner ZRM 6013+ RL-Qd is a high-performance, portable retroreflectometer designed for accurate measurement of night visibility (RL) and day visibility (Qd) of road and airport markings. Part of the Screening Eagle Technologies – Road Safety portfolio and Swiss Made, it delivers ultrafast, reliable results in both field and laboratory environments.

Featuring a bright 5.7″ transflective color touchscreen, robust construction, and intelligent optics, the ZRM 6013+ enables quality control and compliance testing on all types of road markings in dry or wet conditions, at any time of day or night. Its large internal memory and compatibility with MappingTools software ensure efficient data management, visualization, and reporting for modern road asset workflows.
