Aparat de masurat duritatea Micro Vickers HM-211/221

- The latest electromagnetic force motor used in the loading mechanism enables the test force to be freely slected . It is also possible cu freely set the time for loading and load dwell time. Now your desire for absolute control over indentation size in Vickers hardness testing can be specified. The HM-200 series always offers the test force most appropriate for the specimen material and shape.
- It is possible to perform not only the Vickers hardness test but also a fracture toughness test on ceramics.
- The objectives used enable a very comfortable working distance between the objective and the specimen surface. This greatly reduces the possibility of collision between the specimen and the objective during focusing operations.
- The contrast that is most appropriate for the magnification of the objective can be obtained by manipulating the variale aperture stop in the illumination unit. This makes the indentations clearly visible, leading to less vriation and reducing the chance of error when measuring the diagonal legths.
