Mobile Instruments: Laserlux® CEN 30 for Pavement Markings

The Laserlux® CEN 30 mobile retroreflectometer is the most complete and sophisticated mobile highway retroreflectometer system on the market today. Featuring proven optical head technology, the system objectively measures the retroreflectivity of pavement markings using a scanning laser source. The system ensures that measurements are collected quickly and accurately by incorporating new high-speed data acquisition electronics and software, and precise angular settings of illumination and angle of observation.

The system provides real-time pavement marking reflectivity and can be used either day or night at variable traffic speeds. Designed with CEN 30-meter geometry, the system has a scan width of 1.1 meters, giving the user both contrast and retroreflectivity measurements anywhere within the scan width.

Features include Windows 98/ME/NT/2000/XP-based graphical data logging software with a GPS for location data logging, mounting brackets for left- or right-side vehicle measurements, a forward-looking video camera with cab-mounted monitor for driver guidance and cab-mounted video recording camera with data overlay.
