Visual Hardness Tester

The visual hardness tester measures hardness by observing the indentation size through an optical magnification system and converting the imprint left by the indenter on the material surface into a hardness value. It is used for hardness testing of soft materials such as coatings and plastics, and results are obtained by directly reading the scale or comparing with standard charts during operation.
Selection
When selecting, consider the compatibility of the material's hardness range with the indenter type: use Rockwell indenters for metallic materials and Shore indenters for elastomers. Verify that the instrument's measurement range covers the hardness value of the tested object. Choose a mechanical type for environments with low vibration and a digital display type if data output is required. Pay attention to indenter cleanliness and regular calibration.
