Multi-Angle Traffic Signs Retroreflectometer

Portable multi-angle detector for measuring night visible photometric properties (coefficient of retroreflection RA and R’) of retroreflective materials on spot. It is a convenient instrument used to test traffic signs for highway, railway, aviation or reflective markings on trucks, to ensure retroreflective markings meet the requirements of relevant standards.
