Abrasion-resistance test device crockmeter GT-KC01

Product overview
The GESTER Rub Fastness Tester GT-KC01 evaluates color fastness, rubbing and abrasion resistance of leather, plastics and textile materials. It reproduces reciprocating wear under controlled pressure using white wool felt as the abrasive to quantify color change, fading and staining. The instrument supports both dry and wet test modes and is suitable for manufacturers and quality control laboratories assessing durability and color fastness.

Highlights / uses

• Specifically designed for color fastness to rubbing and abrasion testing of leather, plastics and textiles
• Reciprocating mechanism simulates real-world wear under defined pressure
• Capable of dry and wet abrasion tests
• White wool felt abrasives used to measure color change and staining
