Retroreflector Meters

Features

Measurement of traffic signs according to ASTM and DIN 67 520
The Retro Checker RC 2000 is a convenient rechargeable measuring instrument for the determination of the coefficient of retro reflection R' of retro reflective materials(nighttime visibility.)

Additional equipment like data storage, GPS (Global Positioning System)and barcode reader make the RC 2000 the ideal instrument for building up a traffic sign inventory.

To carry out a measurement, the RC 2000 is positioned directly onto the traffic sign under examination and it immediately delivers results with laboratory precision. GPS data for localization and barcodes for identification of traffic signs are recorded and stored automatically and can be transferred to a PC via serial interface.

The Retro Checker RC 2000 can be used for all types and colors of retro reflective sheeting.
