Product Overview

SMV-401 Micro Vickers & Knoop Hardness Tester

◆The Micro Vickers and Knoop hardness tester SMV-401 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 Knoop hardness. The hardness is calculated out with tested value of diagonal to be input into the unified computer.
◆The Micro Vickers and Knoop 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.
◆The hardness testing is divided into two parts: the first part, using the known test force to drive the diamond indenter into the surface of the material to be tested; the second part, the client has measured the length of the diagonal of the indentation, and input the data into the main computer, which will calculate out the Vickers hardness value or the Knoop hardness value.
