Retroreflectometers are robust, long lasting and advanced instruments, designed for professionals using the latest developments in light and sensor technology for measuring the retroreflection of road markings.
With the gradient index technology and patented optical system, the retroreflectometer can measure all types of flat and profiled markings.
The sensor response, combining the CIE eye response and the CIE illuminant A, meets both CEN and ASTM requirements for profilecapacity and colour.
