Buchholz Hardness Tester

The Buchholz hardness tester applies a fixed pressure to the coating surface through an indenter, measures the length of the indentation after it is formed, and reflects the coating's resistance to indentation. It is used for hardness testing of soft materials such as coatings and plastics, and for evaluating the mechanical properties of coatings after drying.
Selection
When selecting, consider the hardness range of the test material, ensure the indenter specification matches the sample thickness, check the calibration status of the instrument, ensure operational convenience meets daily testing needs, and verify that environmental adaptability aligns with laboratory conditions.
