RoadVista, a Gamma Scientific company, has announced the official release of their Model 933 Retroreflectivity Goniometer system for testing sign sheeting and high visibility clothing. The benchtop four-axis goniometer system serves as an inspection Quality Assurance (QA) instrument for quickly testing retroreflection at multiple measurement geometries.

The 933 retroreflectivity system measures retroreflection (RA) and the retroreflective color of materials. A 3-axis motorized goniometer features continuously adjustable ß1 (-60° to 60°), ß2 (-60° to 60°), and e (-180° to 180°) angles. The goniometer system also has a motorized, continuously adjustable a (0.2° to 2°) angle mechanism and color detector with observation angle fixed at 0.33°.

The primary light sensor for the 933 meets ASTM E1709 requirements with the CIE standard human eye response in conjunction with the CIE illuminant “A” lamp. The photometric detector accurately measures different colors without the need to calculate correction factors, while its color detector accurately calculates the CIE1931 color coordinates.
