The crockmeter is used for the determination of colour fastness of textiles to rubbing under either dry or wet conditions. Our motorised crockmeter is an advanced microprocessor based version of the regular crockmeter, and is automatically operated by a motor. It consists of the main unit having an oscillating arm with a finger, which rubs over the test specimen under a specified load. The rubbing finger is cylindrical in shape and has a flat base, which is covered with a piece of standard white abradant cloth which picks up the color lost by the test specimen. A preset counter with digital display is provided to enter the desired number of rubs.
