fingertip hand abrasion tester

Functionality of a product is considered as a matter of course, so the perception of quality is determined

primarily by the visual appearance. Damage to a surface by the human hand is one of the main reason for disturbance of the products quality perception.

The hand abrasion is a very complex chemical and mechanical combination. By touching a surface the human hand performs a mechanical strike followed by a push-slide force. The human hand consists of a visco elastic material containing a rough

and structured surface. In addition, sweat or hand cream creates a severe chemical environment.

Hand Abrasion Tester / soft-chemo-mechanical fingertip & hand abrasion tester is designed to do

real life testing of finished products or lab samples in regards of resistance to hand abrasion. The

set-up of it  is exactly reproducing the complex chemo mechanical system of the human hand abrasion according to international standards.

The flexible design of the tester allows various options and delivers reproducible results.
