What are the advantages of using a digital Vickers hardness tester?

Digital Vickers hardness testers are used for the measurement of Vickers hardness values of thinner workpieces. A diamond indenter in the shape of a regular quadrangular pyramid is used to press into the surface of the specimen under the action of a test force. After maintaining the force for a specified period, the test force is unloaded, and the length of the diagonal of the indentation on the specimen surface is measured.
The indentation of the digital Vickers hardness tester test is square, with clear contours and accurate diagonal measurements. Therefore, the Vickers hardness test offers very high precision among commonly used hardness testing methods, and its repeatability is also excellent, which is superior to Brinell hardness testing.
The measurement range of the digital Vickers hardness tester test is extensive, capable of measuring almost all metal materials used in industry today, from very soft materials to very hard materials.
The advantage of the digital Vickers hardness tester test lies in the fact that its hardness value is independent of the magnitude of the test force. As long as the material is uniform in hardness, any test force can be selected, and the hardness value remains unchanged. This is equivalent to having a unified scale across a very broad range of hardness, which is superior to the Rockwell hardness test.
