In pharmaceutical tablet production different ingredients are used. Changing the concentration of these ingredients affects the color of the tablet. The color gradient varies from white and beige to yellow. The colorCONTROL ACS7000 online color measurement system with a 30° sensor head accurately measures the slightest color difference, particularly those finely-graded color shades between white and beige. This color information provides a statement about the quality of the ingredient composition in the tablet produced. The colorCONTROL ACS7000 online color measurement provides a measurement accuracy of ∆E=0.08 at a measurement frequency of 2kHz.
