Offered exclusively in North America by TAPCO, Delta's RetroSign® GR3 retroreflectometer is a handheld instrument for measuring retroreflection of traffic signs. The GR3 measures the coefficient of retroreflection, RA, and meets all U.S. and European standards, including the FHWA MUTCD.
The unique triple geometry facilitates simultaneous measurements at various observation angles as proposed by ASTM. The RetroSign GR3 measures simultaneously at observation angles of 0.2 , 0.5
and 1 degrees. The internal memory stores up to 250,000 readings.
The photometric filter in the RetroSign GR3 is the
most precise, sensitive and durable filter in the world.
In combination with the point aperture geometry,
it gives readings with laboratory precision for all colors and types of retroreflective sheeting and will determine if a microprismatic sign sheeting material has been applied correctly.
The RetroSign GR3 has a built-in precision WAAS
GPS and an attachable RFID reader. Due to its
robustness, RFID has become the optimum choice
for field asset ID tagging and has proven itself superior
to other technologies.
The RetroSign GR3 is designed to easily interface
with current and future ID tagging and asset management systems. When used with TAPCO's Datalink™ and SignIT™ software programs your complete traffic sign inventory data can be
stored in minutes.
