Overview
Cometech QC-637 Dropping Impact Tester evaluates surface impact resistance by dropping a designated steel ball from a defined height onto the specimen placed on the platform.
After impact, the operator observes the specimen’s damaged condition on the surface to assess performance and compare materials.
Test height and steel-ball size can be adjusted according to the specimen and test conditions, making the setup flexible for different products and materials.
