The RetroSign retroreflectometer is a hand held instrument capable to measure accurately and
reliably the retroreflection properties of road signs and retroreflective materials.
The RetroSign measures the retroreflection (with direct read out of the coefficient of
retroreflected luminance in cd/lx·m²) according to international standards.
The use of a proprietary gradient index filter technology and the patent
pending optical system design ensures accuracy comparable to laboratory measurements for all types
and colours of retroreflective materials. Only one white calibration standard is needed.
Data storage in internal memory provides for registration of measurement results and
corresponding supplementary data. Serial interface RS232 is included for extended control, calibration and data
output.
The RetroSign is powered by a rechargeable battery pack with a capacity corresponding to typical
more than 1000 measurements. A mains powered battery charger is supplied as standard accessory.
