Multi-Finger Scratch and Wear Tester
This instrument uses a tungsten carbide scratch to detect surface damage from physical contact. It assesses wear resistance of plastic parts in automotive interiors/exteriors, hard materials, paint, ink, soft metal, and carpet.
Technical Specifications
Overview
Precision Surface Resistance Testing
The Multi-Finger Scratch and Wear Tester is a precision instrument designed to measure the susceptibility of material surfaces to scratching, marring, gouging, and engraving. By utilizing a five-finger scratching mechanism, it simulates real-world physical damage that falls outside the category of ordinary wear. This equipment is essential for quality control and R&D, particularly for evaluating plastics, coatings, and rigid organic materials in automotive and industrial applications.
