Color Reader Whiteness Index
Model CR-14


Check the whiteness of foods or raw materials.
Measure solids, pastes, or powders.

Whether a food's color is good or bad can influence consumer purchases. Since color variations of white are especially obvious, it has become increasingly important to control color from raw materials through the manufacturing process. Furthermore, there is a growing need to quantify what effect storage during transportation has on the whiteness of a product.
