Pencil Hardness Tester

Use a pencil to test the hardness of coating scratches, and use it with pencils of different grades of hardness.

Shore Hardness Tester

It is widely used in the hardness determination of rubber and plastic, and can be divided into three types: A type, C type and D type.

Pendulum Hardness Tester

Used to determine the hardness of organic coatings, and the results are expressed as a percentage.

Scratch Tester

The strength, hardness, and adhesion of the coating are characterized by the penetration resistance of the paint film sample coating when it is scratched by a stylus.

Indentation Hardness Tester

Not only can it directly test the microhardness of the material, but also can directly test the fracture toughness and residual stress of the interface system between brittle materials and brittle coating film materials.
