The Glass Scratch/Abrasion Tester is used to test the scratch and abrasion resistance of glass. This instrument uses a counter to set the number of rubbing cycles and a speed controller to adjust the operating speed of the rubbing head to meet the customer's actual testing needs. During the test, a 10mm*10mm rubbing head equipped with steel wool is used. Adjustable weights adjust the pressure load of the rubbing head to rub the glass. After the test, the sample is removed and its scratch and abrasion resistance is evaluated.
Applications
Automotive Glass: Assesses windshield durability against environmental wear.
Consumer Electronics: Tests smartphone screens, tablet covers, and display panels.
