The KK-03 Scratch Resistance Tester is designed for low-load and micro-scratch evaluation of delicate surfaces such as thin films, coatings, and precision materials. With precise low-force control and laser depth measurement, you can accurately assess early-stage scratch damage and surface sensitivity.
Low-load scratch testing of thin films and coatings
Surface sensitivity evaluation of decorative and functional layers
Scratch assessment of electronic and optical materials
Research on micro-scratch behavior and surface initiation damage
Material development requiring fine load resolution
