The Zehntner-retroreflectometer ZRM 6013 simulates the conditions under which road markings are seen at night (RL) by a vehicle driver driving with dipped headlights. The day visibility (Qd) of road markings under typical or average daylight or under street lighting is simulated with diffuse illumination. This renders an objective determination of retroreflection possible.
- Determination of the night visibility (RL) and day visibility (Qd) of road markings as well as ambient temperature and relative humidity combined in one compact instrument.
- For all types of road markings - smooth, textured, profiled, colored, with or without aggregates and reflective beads; on wet or dry roads.
- With extented memory, interfaces for PC and printer.
- High long-term stability ensures constant measuring accuracy and thus reliable measuring results. Possible deviations caused by damages or soiling of the calibration standard or the equipment will be shown automatically.
- Approved by independent test laboratory BASt Germany (no BASt-V4 22/2206).
| Application areas |
- For national road authorities, road laboratories, manufacturers of road marking materials, contractors and expert witness
- Determination of night and day visibility of road markings, ambient temperature as well as relative humidity in dry or wet condition, at any time of the day or night, on the road or in the laboratory
- Control of road markings after application and during the warrantly period
- Decision on required renewal

| Features |
- With a press of the button several values
- Menu-guided in several languages, easy to operate
- PC and printer download, printout of a detailed test report ( a.o. user ID, date/time, location, specification of road marking, average value) on an A4 size paper, either with an office or portable printer
- Off-the-line operation owing to built-in powerfull accumulator, for 400 measurements per day, the accumulator has to be recharged only once a month
- LED with high life time (over 500'000 measurements)
- Automatic lightness supervision and correction
- For all type of road marking paints, marking foils, thermoplastic and cold plastic materials
- At markings with profiles up to 5 mm just putting on and measuring
- Markings of different colors can be measured without recalibrating the instrument
- Automatic calibration using the supplied standard
- 2nd calibration standard can be programmed
- Simple positionning for RL and Qd measurement on the same measuring area without repositionning
- Free software update and program for PC (RetroTools software). RetroTools is available for Windows 98 SP1, NT 4.0 SP5, 2000 SP2 ans XP versions. In addition, the Internet Explorer 4.01 or higher is required
- Data transfer to Microsoft Excel for statistics
- Optional availability of wheels, remote control incl. adjustable handle for a higher user convenience in the field; without tools easily to mount and to remove
- Optional delivery of GPS unit (Global Positioning System); easilty to mount and to remove
