KONICA MINOLTA CR-20 Color Reader – A Combined Successor To the CR-11, CR-13 and CR-14

Easy-to-use, lightweight and affordable colorimeter. Ideal for entry level absolute color measurement and inspection.

The CR-20 color reader measures the color and whiteness of food or raw materials in paste, solid or powder form. It boast a large LCD screen that displays measurement results from one to eight color spaces/colorimetric indexes including L*a*b*, L*C*h*,Yxy, Munsell, WI (CIE/ASTM E313-96). Tint (CIE/ASTM E313-96) and YI (ASTM E313-96)

The CR-20 color reader is built with a protective glass cap. This allows direct measurement of pastes, powders, or wet objects without needing to fill a cell. This device is printer-ready with USB connectivity in case you need a hard copy of your results. With built in software the CR-20 will allow you to take multiple measurement and average them with one touch averaging button, perfect for uneven color objects.

The instrument can be utilized in order to control from raw materials through the process of manufacturing. It can also quantify the effect that storage has inflicted on the whiteness of a product during transportation. The CR-20 fits comfortably in the palm of your hand. It is both battery operated and light-weight. This CR-20 can also be connected to an AC-Adapter for external power.
