Needle Hardness Tester

The needle hardness tester measures the hardness value by vertically pressing a spring-loaded steel needle into the material surface and converting the indentation depth. It is used for testing the scratch resistance of soft materials such as coatings and plastics, and finds applications in coating curing monitoring and product quality control.
Selection
When selecting, consider the material's hardness range matching the instrument's measurement range, ensure the tip specifications correspond to the testing standards, verify the accuracy of the spring force and its calibration certificate, ensure the operational convenience and data output methods meet daily testing needs, and confirm the environmental adaptability aligns with laboratory conditions.
