Visual Appearance ColoriMeter

The appearance colorimeter illuminates the sample with a standard light source, and the sensor receives the reflected light and converts it into an electrical signal. The processor analyzes the spectral data to derive color values. It is used to measure the surface color of objects, and in the paint and ink industry, it is employed for color matching and quality control. In the plastic and printing industries, it is used to detect color consistency in products.
Selection
