ZRM 1013 Retroflectometer

EN 1436 - ASTM E 1710

Portable, sturdy precision measuring instrument for the determination of the night visibility (RL) and/or the day visibility (Qd) of road markings


The Retroflectometer ZRM 1013 is a portable, precision measuring instrument for the determination of night and/or day visibility of road markings - depending on the version.

It is powered by an intelligent rechargeable battery.


  • Night and/or day visibility determination dry and wet, during daytime, on the road or in the lab
  • Long term product comparison, product evaluation
  • Control of road marking after application, during warranty period and for renewal decision making
  • For National Traffic Authorities, road labs and manufacturers of road construction materials

  • ZRM 1013 RL for the determination of the night visibility
  • ZRM 1013 Qd for the determination of the day visibility
  • ZRM 1013 RL / Qd combined instrument for the determination of night and day visibility
  • The observation angle of 2,29� corresponds to an observation distance of 30 m by a motorist viewing under normal conditions.

    The measuring area is illuminated with 1,24� for the determination of the night visibility and diffused for day visibility.


  • The determination of both night and day visibility are possible at any time of the day - in full daylight as well as by night.
  • Possible straylight is being compensated.
  • Easy and quick calibration.
  • Suitable for all kinds of road markings: Road marking paints, thermoplastic and cold plastic material, pavement marking tape.
  • Suitable for road markings with and without reflective beads.
  • Suitable for glass and ceramic beads.
  • Likewise suitable for plane and textured markings.
  • For measuring the visibility of dry, humid and wet road markings.
