Hardness testing technologiesBack to overview
It is hard to imagine present-day hardness testing machines without automatic evaluation of hardness indents. It dramatically reduces operator influence in hardness tests and improves the comparability of results.
A hardness indent is evaluated automatically in depth measurement methods by means of a depth measurement sensor in combination with the test software. The depth measurement gauge determines a depth differential during the indentation process with the indenter. Then the test software uses this differential to immediately calculate the hardness value automatically. Following indentation, the determined hardness value is shown on the display of the hardness testing machine.
