Universal Finger Abrasion Tester EN 60068
The Universal Finger Abrasion Tester simulates the mechanical and chemical interactions between a human finger and a surface. It evaluates the effects of friction, body oils, sweat, and potential chemical reactions on material surfaces over time. The device uses an electronically controlled piston (artificial finger) to replicate realistic wear patterns, providing precise, reproducible results for product durability and surface performance testing.

Test Procedures
Mount the artificial finger piston onto the test unit.
Fix the material sample securely on the test platform.
Set the desired load, friction diameter, and cycle count.
Initiate the test program; the linear motor applies precise cyclic motion to simulate wear.
Monitor results via the software; after completion, remove the sample for evaluation of wear, abrasion, or chemical effect.
