Spectral Colorimeter CS-A12
The CS-A12 Spectral Colorimeter, known for its high precision, employs a spectral measurement working theory that significantly enhances colorimeter accuracy. Its superior leather design increases friction to prevent finger sliding. This colorimeter features multiple light sources for measurements and includes metameric index, staining fastness, and color fastness capabilities, making it especially valuable for color measurements in the textile industry.
