hardness tester


A hardness tester is an instrument used to determine surface hardness. Each of these instruments uses a standard measurement. Its measuring principle is based on the piercing of the diamond indicator into the material that is being measured or based on a calculation relating to a rebound force after hitting the testing material. Each testing approach has its advantages and will provide a precise material hardness measurement in accordance with the approved technical specification of the hardness testing tool.


Benefits of Hardness Testing Instruments

Hardness testing instruments are widely used to measure the hardness of the different kinds of materials. Some of the main benefits of using hardness testers include:

Hardness testing instruments like Rockwell offer a non-destructive test. Meaning that the material is not destroyed, it can be used to do several other things after the hardness test is completed.

Many hardness testing instruments offer fast hardness testing and are perfect for bulk hardness testing specimens on the product line.

With the use of testers, testing is easy and quick. This is because of its non-complex nature.

How does hardness testers work?

The indicator is set on the hardness testing instrument to the reading position. The next step is to load the instrument. The indenter of the instrument is then set to make contact with the test specimen at an angle of 120 degrees. The next step will be to preset the required level of pressure that will be applied to the test material. Next, free the indenter to make an impact with the test specimen. Then take a record of the indentation. This record will be used to compare the next test.
