Digital Microhardness Tester

The digital display microhardness tester applies a fixed load to the specimen surface through a diamond indenter to create an indentation. The optical system measures the diagonal length of the indentation and automatically calculates the Vickers or Knoop hardness value. It is used to test the hardness of metals, coatings, and small components, and is commonly found in laboratories for material quality control and process verification.
Selection
When selecting, consider the hardness range of the test material and the matching requirements of the indenter and load; the magnification of the objective lens for observing indentations and the measurement accuracy must meet standards; the sample thickness should be at least 10 times the indentation depth; the digital display function should focus on data output interfaces and repeatability error control.
