Measurement of the Coefficient of retroreflected luminance RA (nighttime retroreflection) of road traffic signs, high visibility clothing, license plates and reflective tapes. Further entrance angles are offered as easy changeable front adapters for speciel measurement purposes: 10°, 20°, 30°, 40° and 45°. The instrument uses point aperture geometry which enables the user to determine if direction sensitive microprismatic sheeting is correctly positioned on a sign.

Measurement of the Coefficient of retroreflected luminance RA (nighttime retroreflection) of road traffic signs, high visibility clothing, license plates and reflective tapes. Further entrance angles are offered as easy changeable front adapters for speciel measurement purposes: 10°, 20°, 30°, 40° and 45°. The instrument uses point aperture geometry which enables the user to determine if direction sensitive microprismatic sheeting is correctly positioned on a sign.

The GRX retroreflectometer measures nighttime retroreflection of traffic signs, high visibility clothing, license plates and reflective tapes. It is a handy instrument for use on the roads and in production. GRX is the new instrument in the RetroSign family that over the years has become the most widely used solution worldwide for measurements of traffic sign retroreflectivity and a de facto standard in many regions of the world.

GRX is intuitive in use. Measurements are taken in one second and data is easily transferred to a PC or a tablet. Built-in options for photos of signs, barcode reader, QR code reader, GPS, instrument rotation and tilt, sign facing direction and MUTCD sign library for automatic pass / fail of sign performance extend the instrument versatility significantly.
