Retro Reflectometer Vertical


Retro Reflectometer Vertical is a handheld instrument for measurement of the coefficient of retroreflection (RA) of road signs, safety clothing and other materials. The innovative optical system can measure up to 4 (four) simultaneous observation angles.

The entrance angle (β) can be fixed ( −4° / +5° ) or it can be continuously adjusted by the operator.

The combination of adjustable entrance angle with the exclusive quadruple simultaneous observation angles allows precise determination of retroreflection according to all international standards:

  • ASTM E1709 (0.2°)
  • ASTM E2540 (0.5°)
  • EN 12899-1 (0.33°)
  • ECE104 (0.33°)
  • ISO 20471
  • UNE 135340 (0.2°, 0.33°, 1.0° ,1.5°)

Retro Reflectometer Vertical measures the night visibility RL, the Day Visibility Qd, the visibility under wet RL wet and continuous wetting conditions RL rain of road markings. The patented retroreflectometer optical system, combined with CIE eye sensor response, allows precise measurement of all types and colors of road marking materials, even profiled markings up to 15 mm.

Fast measurements: 0.6 s for RL, 0.9 s for RL + Qd........immediately ready for next measurement.
