CR-20 Color Reader
The handheld CR-20 (combined successor to the CR-11, CR-13, CR-14), color reader, measures the color and whiteness of foods or raw materials in paste, solid, or powder form. It boasts an impressive LCD screen that displays measurement results from one of eight color spaces/colorimetric indexes including L*a*b*, L*C*h, Yxy, Munsell, WI (CIE/ASTM E 313-96), Tint (CIE/ASTM E 313-96), YI (ASTM E 313-96).
This instrument can be utilized in order to control color 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, so it is extremely portable. This unit can also be connected to an AC adapter for external power.
This device is affordable and easy-to-use. It is particularly ideal for industries that are just beginning to measure color or need multiple devices that are reliable yet affordable. The functionality of this instrument is user-friendly and does not perform any unneeded processes. This makes things simple. There are 3 easy steps to operate the CR-20, switch on power, perform white calibration, and measure the sample. All color measurements are taken using conditions of the standard illuminant D65 and 10 degrees observer while offering a Xenon lamp light source for longer life and more stable readings.
The CR-20 color reader has 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.
