ZRM 6014

Day and night visibility measurement of road markings with retroreflectometry

The ZRM 6014 RL-Qd is a premium handheld retroreflectometer that combines night (RL) and day (Qd) visibility measurement of road and airport markings with ambient temperature and humidity monitoring. Equipped with a vibrant 5.7″ color touchscreen, fold-away telescopic handle, and wheels, it delivers ultra-fast ~2-second measurements with exceptional portability and ergonomic use. Standard calibration is traceable to METAS, certified by StrAus-Zert, and the device supports optional GPS, high-resolution imaging, compass/level-meter modules, and onsite printing for versatile data capture and reporting.
