| The Zehntner-retroreflectometer ZRM 6006 measures the night
visibility (RL) of road markings as seen by a vehicle driver driving with dipped headlight. The illumination simulates the dipped headlights of a vehicle. The day visibility (Qd) of road markings under typical or average daylight or under street lighting is measured with diffused illumination. This makes an objective determination. |
- Budget priced basic instrument for the determination
of night visibility (RL) and day visibility (Qd)
of road markings as well as ambient temperature
(°C/°F) and relative humidity (rH %) combined in
one compact instrument.
- For all types of road markings.
- For profiles up to 5 mm (0.2“), just put on and
measure; additionally, significantly higher profiles
can be measured with instruction.
- In accordance with EN 1436 (for RL and Qd), ASTM
E 1710 (for RL), ASTM E 2302 (for Qd) ASTM E 2177
(for RL wet).
- Factory calibration with a calibration standard
traceable to the independent accreditation body
METAS, Switzerland.
|
- For road authorities, road laboratories, manufacturers of road marking materials, contractors and expert witnesses
- Determination of night (RL) and day visibility (Qd) of road
markings, ambient temperature as well as relative humidity in dry or wet condition, at any given time of day or night, on the road or in the laboratory
- For all types of road markings paints, marking tapes, thermoplastic and cold plastic materials - whether smooth, textured, profiled, coloured, with or without aggregates / reflective beads
- Getting the best value - control of road markings after application and during the warranty period
- Checking for road marking maintenance
- For jurisdictionally relevant measurements in case of litigation
