Automatic Scratch Tester

This motorized apparatus is dedicated to coating hardness evaluation based on scratching resistance method. A test panel is clamped and slowly moved whilst a stylus or alternative tool scratches the surface. Depending on test procedures, specified or variable loads can be applied to obtain different degrees of failure, from trace to destruction. A voltmeter indicates the contact of the tool with the metallic sample substrate.

  • Working table can be moved left and right—convenient for measuring different areas in the same panel
  • Sound-light Alarm system for puncturing through sample panel---more visual
  • High hardness material needle-more durable
