TheUniversal Finger Abrasion Testeris a high-precision instrument designed to simulate wear and abrasion caused by human fingers, nails, teeth, and other contact surfaces on various materials. You can replicate real-life mechanical and chemical interactions, including exposure to liquids such as sweat, hand cream, sunscreen, detergents, and toothpaste. This tester quantifies surface wear, scratches, and coating durability, providing reliable data for quality evaluation across multiple industries.
Applications
Universal Finger Abrasion Tester can simulate virtually all wear processes involving products and fingers/skin, and realistically replicate liquid environments such as human sweat, hand lotion, sunscreen, detergents, toothpaste, and other liquid media.
This device can simulate wear processes including: finger abrasion, nail scratches, tooth wear, sole abrasion, and industrial scratches. When human fingers, skin, teeth, and other media come into contact with various products, they cause wear on the material surfaces. This wear significantly impacts product quality and performance.

Test Procedures
1. Equipment Preparation
Verify the tester is properly powered and connected (110V/230V).
Ensure test heads, abrasion cloths, and liquid reservoirs are properly installed.
Confirm test parameters: load, friction path, number of cycles, and test medium (dry or liquid).
2. Sample Mounting
Secure the sample material on the fixture, ensuring flat and stable contact with the test head.
3. Test Execution
Select the test program (dry abrasion, liquid abrasion, or customized cycles).
Start the test; the system applies the defined load and friction path automatically.
Monitor the test progress via control software; record cycles, force, and abrasion results.
4. Data Analysis
Evaluate material wear, scratches, and surface degradation.
Compare results against predefined quality or industry standards.
