    AI-621K Surface Hardness Abrasion Tester
  • Its main purpose is to test surface treatment of fastness, hardness and wear resistance of characteristics. Like painting, plating, coating and dyeing of treatment of wear and fade conditions. It usually uses white cloth, sand bar, steel wool of wear specimen material. Stepper motor drive uses constant velocity friction with traditional harmonic game by test stroke limit agencies. It also can base on various standard requirements to set up test condition. Like speed, stroke, specimen shape, abrasion head type and load.
