Double Needle Hardness Tester

The dual-needle hardness tester measures the difference in indentation depth by pressing two conical indenters into the material surface under a fixed pressure, converting this into a hardness value. It is used to test the scratch resistance of soft materials such as coatings and plastics, and in quality inspection to evaluate the degree of coating curing and wear resistance.
Selection
When selecting, consider matching the material's hardness range with the instrument's measurement range. The tip size should correspond to the testing standards. Verify the accuracy of the indenter and the stability of the spring force value. The body should be corrosion-resistant and equipped with a flat base. Check the calibration certificate and ease of operation.
