Manual Crockmeter from China

Y571M Manual Crockmeter (Rubbing Fastness Tester) is designed to determine the color fastness of textiles (pile fabrics excluded) to dry or wet rubbing. It provides a reciprocating rubbing motion simulating the action of a human finger and forearm. The 16mm diameter crocking finger covered with a cotton test cloth moves back and forth on the textile specimen with a downward force of 9 Newton. Manual drive, simple operation, and count automatically.
