A hardness tester is a device used to measure the hardness of a material. Hardness is a measure of a material’s resistance to deformation or scratching. The harder a material is, the more resistant it is to scratches and other forms of damage.
Hardness testers come in various shapes and sizes and can test the hardness of different materials, including metals, plastics, and ceramics. They are used in multiple industries, such as the automotive, aerospace, and construction industries. They can be used to test the hardness of a material before it is used in a product or to test the hardness of a product after it has been used.
There are a variety of hardness testers on the market. Some are portable and can be used in the field. Others are benchtop models that are used in a laboratory setting. The type of hardness tester that you need will depend on the application that you are using it for.
The most common type of hardness tester is the Rockwell hardness tester. This type of tester uses a diamond-tipped indenter to make an indentation in the tested material. The indentation depth is then measured and converted to a hardness value.
The testers are both manual and automatic versions and can be used to test materials of any thickness. There are two main types of Rockwell hardness testers: the Rockwell Superficial Hardness Tester and the Rockwell Automatic Hardness Tester.
The superficial tester tests the hardness of only a few millimeters thick materials, such as thin metal sheets. The automatic tester tests the hardness of thicker materials, such as bars or plates. Rockwell are used in various industries, including automotive, aerospace, and electronics. They are often used to test the hardness of components subject to high stress levels, such as engine parts or turbine blades.
