About This Product

■SummaryModel 933 is a goniometric retroreflection measurement system. It offers 4-axis adjustment with a motorized stage and provides measurements in accordance with the ASTM E1709 standard based on CIE. The adjustable angle ranges are observation angle α (0.2° to 2°), incident angle β1,β2 (-60° to 60°), and rotation angle ε (-180° to 180°). It can be used standalone without the need for a PC. Operations and measurement results are performed using the touch panel. Measurement data can be saved in internal storage, and up to 30,000 measurement data can be saved. It can also be connected to a PC via USB and perform automatic measurements using ASCII commands.

The Goniometer Retroreflection Measurement System Mode l 933 is a device that measures retroreflection (RA) and retroreflection color. A three-axis electric goniometer that can continuously adjust the incident angle β1 (-60° to 60°) /β2 (-60° to 60°) and the rotation angle ε (-180° to 180°), as well as the observation angle α. Equipped with a mechanism that allows continuous electrical adjustment (0.2° to 2°). The observation angle of the color detector is fixed at 0.33°.

The primary light sensor has CIE standard human eye responsivity according to CIE “A” light source and meets ASTM E1709 requirements. Photometric filters allow you to accurately measure different colors without calculating correction factors. The color detector is equipped with a 3-channel RGB sensor to generate CIE1931 chromaticity coordinates.

The device can be used as a standalone device, with internal memory capable of storing more than 30,000 measurements and accompanying data. The Model 933 also allows easy control via USB. A large number of measurements can be automated using simple ASCII commands.
