Metallographic Microhardness Tester

The metallographic microhardness tester applies a fixed load on the sample surface using a diamond indenter to form an indentation. The optical system measures the diagonal length of the indentation, and the Vickers or Knoop hardness value is calculated according to the formula. It is used for microhardness testing of metallic materials, enabling analysis of heat treatment effects, coating performance, and grain hardness distribution.
Selection
When selecting, consider matching the hardness range of the material with the load range, and ensure the specimen size corresponds to the working distance of the objective lens. Automatic turret switching between the indenter and the objective lens is required. Pay attention to the measurement accuracy of the indentation diagonal, and ensure the software includes hardness conversion and statistical functions. Choose a manual or automatic loading system based on the testing frequency, and verify the certification integrity of the indenter and standard blocks.
