Finger Tip Abrasion Tester
Category：Interior Material Tester
Introduction
The Finger Tip Abrasion Tester is designed to simulate human fingertip contact on a test specimen by applying a defined load, stroke, and speed. It evaluates the abrasion resistance and durability of surfaces subjected to frequent tactile interaction, such as control panels, touch surfaces, switches, and coatings.
Application
The applied load is set using dead weights, and the scrub (abrading) distance is adjustable from 1 to 4 mm, allowing precise adaptation to different test materials and geometries. This tester supports a wide range of applications, including mechanical abrasion and chemo-mechanical testing when liquids such as artificial sweat, hydraulic oil, or cleaning solutions are applied to the test fabric.
