LTL-M2
Retroreflectometer instrument for measuring retroreflection of road markings based on the latest technological developments. Easy to calibrate and operate, robust and long-lasting, small, light and with a range of support features.
The LTL-M2 retroreflectometer simplifies retroreflective measurements at traffic speeds. By removing the need for handheld tools, it enhances safety and reduces risks. Capturing key parameters like night visibility RL, daylight contrast, marking width and RRPMs, it ensures a thorough assessment for improved driver guidance. With dual measurement heads, survey efficiency is doubled, saving time and resources. The LTL-M2 can be purchased as a single or dual measurement system. Fully backwards compatible, it integrates seamlessly with existing LTL-M systems.
The LTL-M2 showcases efficiency by covering over 3,000 kilometres of road markings each week. Its 1×1 square metre viewing field ensures thorough coverage. Leveraging advanced camera-based techniques and real-time digital image processing, the retroreflectometer provides accurate measurement results under diverse driving conditions. This efficiency saves time and highlights its adaptability to real-world road scenarios.
The platform for the graphical user interface enables the operator to use any touch-screen device running a web browser, both wired and wireless.
The intuitive design enhances operator efficiency by simplifying access to critical functions, ensuring smooth measurement workflows and real-time adjustments.

The LTL-M2 is very quick to mount, release and adjust. No tools are needed: it can be mounted and calibrated in just 15 minutes without additional adjustments. Utilising GPS technology, the LTL-M2 precisely pinpoints measurement locations, providing valuable spatial data. The overhead camera supplements this by offering visual insights during the review of stored data.
The LTL-M2 consistently matches and often surpasses handheld retroreflective measurements. With a repeatability of typically +/-3% and a reproducibility of +/-5%, the retroreflectometer ensures consistent and trustworthy results compared to static measurements. This reliability is foundational for maintaining high standards in road safety and instilling confidence in transportation authorities and road maintenance professionals regarding measurement accuracy.
