On est là pour vous aider!

The precision instrument for the determination of night visibility (coefficient of retroreflection RA and R') of traffic signs and safety garments with measurement of three different observation angles at the same time.

The very first retroreflectometer with LED illumination system and with a 3.5" high resolution colour touchscreen with adjustable display inclination for excellent visibility under all lighting conditions also in bright sunlight.

For all kinds of retroreflective materials and colours with automatic colour indication.

Continously updated average value; additionally each single measurement is stored.

Measurements can be evaluated with the included mapping and data analysis software "Mapping- Tools".

Easy to operate with polyglot menu navigation.

Sturdy construction and ergonomic design.

Factory calibration with calibration standards traceable to the independent accreditation body BASt (Federal Highway Research Institute),Germany.

The calibration certiicate is included.


Night visibility
Retroreflective materials have to fulfil performance limits to the coefficient of retroreflection RA of traffic signs and the coefficient of retrorelection R' of safety garments which are deined within international standards. 


  • for road authorities, road laboratories, expert witnesses as well as manufacturers of traffic signs, license plates, safety garments and their customers
  • determination of the coefficient of retroreflection RA of traffic signs as well as the coefficient of retroreflection R' of safety garments; for all types and colours of retroreflective material
  • field and laboratory use
  • quality control (pass/fail) by manufacturers, by customers on receipt, maintenance and decision on necessary replacement
  • for inventory
