What are the differences between the Vickers HV hardness tester and the micro Vickers hardness tester?

Vickers hardness testers (HV) and micro-Vickers hardness testers both belong to the Vickers hardness testing system, but there are certain differences between them.
From the perspective of the test force range, the test force of a Vickers hardness tester is larger, generally above 1N, and is suitable for larger-sized specimens and routine hardness testing; while the test force of a micro-Vickers hardness tester is extremely small, usually below 1N and as low as 0.001N, and is mainly used for hardness testing of micro areas, such as the microstructure of materials, grain boundaries, and small parts.
In terms of application scenarios, Vickers hardness testers are mostly used for the inspection of finished and semi-finished products in industrial production; micro-Vickers hardness testers are more commonly used in fields such as scientific research and material analysis, allowing for the study of the microscopic hardness distribution within materials. In addition, the optical system of the micro-Vickers hardness tester has a higher magnification, enabling clearer observation of tiny indentations.
The operating principles of the two are basically the same, but the micro-Vickers hardness tester has higher requirements for the operating environment and the skills of the operator.
