Retroreflectometer instrument for measuring retroreflection of road markings

Based on the latest technological developments, the LTL3000 is robust, long-lasting and easy to calibrate and operate. It is also small in size and light in weight. LTL3000 is primarily intended for users who need an instrument for less demanding measurement programs with few central features to support the measurements and who want an instrument that is easy to transport –where retroreflectometer price may also be a consideration.

User-friendly operation

The LTL3000 is specifically designed for users engaged in demanding measurement programmes related to road markings, including those in airport lighting and markings. This handheld retroreflectometer prioritises user-friendliness and ease of operation, catering to professionals who seek precision without unnecessary complexities in their assessments.

The user-friendly interface simplifies operations, making it accessible to individuals prioritising efficiency. This feature is particularly valuable in airport lighting and markings, where precise measurements are essential for aviation safety.

Easy data management and visualisation

The LTL3000 excels in measurement accuracy and streamlining data management. Measurement data can be seamlessly transferred to Excel for efficient storage and processing. Moreover, its compatibility with Google Earth allows users to visualise locations using GNSS coordinates, offering a spatial context to measurements.

Day and night visibility solutions

The LTL3000 measures in RL (coefficient of retroreflected luminance at night, nighttime visibility) and Qd (daytime visibility) of markings under dry and wet conditions, adhering rigorously to European and US standards. These features contribute to the recognition of markings by automated vehicles, ensuring precise navigation. The instrument measures nighttime chromaticity coordinates (x,y) according to ASTM E 2367 and CIE 1931. This specialised approach addresses visibility challenges day and night.

GNSS location coordinates for accuracy

The inclusion of GNSS location coordinates complements precision in measurements. The LTL3000 can utilise GNSS data from four satellite systems—GPS, Galileo, GLONASS, and BeiDou—ensuring accurate location establishment under various measurement conditions. This feature is particularly advantageous in airport environments where precise positioning is paramount for aviation safety.

Calibration for reliability

The instrument comes equipped with an RL and Qd calibration reference and is calibrated in a DANAK-accredited laboratory. Factory-calibrated for the Qd value, the LTL3000 requires re-calibration only when necessary. Instruments with Qd include a calibration marking for verification and calibration purposes. This commitment to calibration ensures the consistent reliability of the LTL3000 in all measurement scenarios.
