Konica Minolta CR-310 Color Measurement

Konica Minolta CR series Chroma Meters are compact, lightweight, portable tristimulus colorimeters for measuring reflected color and color difference in a wide range of industrial fields. Five different CR-300 series models are available to meet the needs of various applications. All CR-300 series models offer improved inter-instrument agreement to allow multiple units to be used for color control both within a company and between companies.

The Chroma Meter CR-310 offers ø50mm measuring area and wide-area illumination/0° viewing geometry for measurements of textured surfaces.
