402SXV micro hardness tester

Description:

1. The Vickers Micro hardness tester is a new-type hardness testing instrument adopting the precision mechanism and photoelectric computer software .The instrument can be used to test the Vickers or knops hardness. The hardness is calculated out with tested value of diagonal to be input into the unified computer.

2. The Micro Vickers Hardness Tester is used for the testing of the metallic materials such as the small components, the thin plates, the metallic foil, the fine-quality electric cables, the thin hardness layers the electroplated layers as well as the non-metallic materials that cannot be tested with a great test force, such as the glass ,the jewelries  and the ceramics .It is particularly important that the tester can be used to the internal hardness of the induction hardened or carburized materials according to the metallic structure.
