Bán máy đo màu
A Color Meter is a digital device used to quantify and measure the color characteristics of a surface or object. It typically measures color in terms of numerical values using standardized color spaces such as RGB (Red, Green, Blue), CMYK (Cyan, Magenta, Yellow, Black), or CIE LMộtb*. By capturing these values, the Color Meter allows users to compare colors objectively, ensuring that products meet the desired color standards and specifications.
Color Meters are non-contact instruments, meaning they can measure color without altering or damaging the surface being analyzed. This feature makes them ideal for a wide range of applications, including quality control in manufacturing, color matching in design, and even scientific research.
