Description
Automatic Scratch Hardness Tester
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.
The voltmeter indicates the contact between the needle and the metallic surface with the help of light and buzzer simultaneously. It also produces the beep noise as indication when the needle and the metallic surface contact with each other. It means that the needle scratched the coating and touched the surface of the substrate.
The Automatic Scratch Hardness Tester is made up of Mild Steel with durable powder coating, sliding plate is made up of mild Steel and the needle is made up of hard stainless steel with a hemispherical ball Ø1mm made up of Tungsten Carbide. It is widely used in paint and coating industries, pipe, steel and fabrication industries etc.
