ColorCheckerDip - a low-cost color sensor for liquids
ColorChecker is an instrument designed for color measurements of dyebaths, e.g. for process monitoring of bulk dyeing and washing machines. It works similarly to a pH probe but outputs color values.
ProcessChecker - a system for controlling liquor ratio, salt and pH
ProcessChecker is an instrument for tightly controlling the key process parameters in the exhaust dyeing of cotton and other cellulosic fibres, thereby increasing lab-to-bulk and bulk-to-bulk color reproducibility. It provides a pass/fail analysis and the required additions of salt, water and alkali to the dyebath, if any.
