aWhat is more, the HR-500 can perform 3 types of hardness tests, not only Rockwell and Rockwell superficial but also Brinell, by introducing our proprietary electronic control technology and providing the Brinell hardness testing load sequence. 而且, HR-500可能执行硬度试验,不仅罗克韦尔和罗克韦尔的3...
Learn about the hardness testing basics and the test methods for Rockwell, Brinell, Vickers, Knoop and Case Depth hardness testing here.
The rotational displacement of the loading means bears a predetermined relationship to the linear dimension of the indentation depth formed during hardness testing of a specimen. The hardness tester further includes electro-optical mechanical encoding means, and further adapted to emit a coded electrical...
