Gardner Color Dial

The Gardner Color Dial is a tool used to measure the color of liquids or materials in a standardized way. It features a rotating dial with a series of colored patches that represent different shades, ranging from light to dark. To use it, a sample is placed against the dial's viewing window, and the closest matching color indicates its color level. This helps ensure consistent quality control in industries like paints, cosmetics, and food production by providing an objective, repeatable color measurement.
