Spectral colorimeter LCS-A12 with high precision, is adopted with spectral measurement working theory which greatly improves the accuracy of colorimeter. The superior leather design, helps in increasing the friction in case of fingers sliding. It comes with multiple light source for measurements & has metameric index, staining fastness, color fastness for color measurements in textile industry.
