Schober Wear and Abrasion Tester

The Schopper abrasion tester fixes the sample in contact with the friction head and performs reciprocating friction under standard pressure to evaluate the wear resistance of the material surface. It is used to assess the abrasion resistance of products such as paper, ink, and coatings, simulating wear conditions in actual use.
Selection
When selecting, consider the type and thickness range of the test material to match the equipment's load and stroke parameters. Confirm that the friction head specifications meet standard requirements, and check the equipment's repeatability accuracy and data recording functionality. Choose between manual or automatic models based on daily testing volume, and ensure that the fixtures are compatible with the sample dimensions.
