MCD Metal Scratch Tester

The MCD Metal Scratch Tester is designed to quantify scratch resistance on metal surfaces, both dry and wet. It measures frictional force during scratching and converts the results into graphical data for precise analysis. Various compressive loads can be applied, allowing evaluation of the surface durability and mechanical properties of metals and coated materials. The instrument is suitable for laboratory research, quality control, and material development applications.
