Delta LTL-M Retroreflectometer

The modern, easy-to-use retroreflectometer

LTL-M, the DELTA mobile retroreflectometer for measuring night visibility (R_L) of pavement markings at traffic speed, is a new generation of mobile systems – and has already achieved a significant market penetration. The system solution outperforms other similar systems by offering better and more sophisticated solutions to mobile retroreflective measurements, including night visibility R_L, daylight contrast, marking width, road stud (RRPMs) presence, etc.

Full coverage at normal traffic speed – day or night

Retroreflectivity measurements can be acquired at normal traffic speed, and during day or night at the user’s preference, hence avoiding dangerous incidents, where an operator must make handheld measurements in a busy road. Over 3,000 kilometers of road can be measured in a normal working week.

A viewing field of 1×1 m2 makes it easy for a driver to cover a line.
