Optical Hardness Tester

The optical hardness tester applies pressure to the material surface using an indenter to create an indentation, measures the diagonal length of the indentation using an optical system, and calculates the hardness value based on the ratio of the load to the indentation area. It is used for hardness testing of materials such as coatings and plastics to determine the degree of coating curing and material wear resistance.
Selection
When selecting, consider the matching of the material's hardness range with the indenter type: use a diamond indenter for metallic materials and a steel ball indenter for soft materials. Determine the load size based on the sample thickness, opting for small loads for thin coatings. Check the clarity of the optical system and measurement accuracy to ensure compliance with industry testing standards. Pay attention to the ease of instrument operation and the compatibility of the data output format with existing workflows.
