Scratch Hardness Test Apparatus used to determine the hardness of a material and its ability to resist scratching. When testing the surface of the coating, by scratch hardness a necessary force is applied to cut through the film to the substrate

It is used for evaluating the resistance of coatings on the substrate by scratching with specific weight and needle. A one side coated panel is clamped at the platform of the automatic scratch tester, specified weight is applied on the weight holding rod and the needle is scratched on the coated surface at a constant speed 30 to 40 mm/s automatically.
