Features :
• Thelatestelectromagneticforcemotorusedintheloadingmechanismhas
enabled the test force to be freely selected (see test force specications
over the wide range of 0.4903mN (0.05gf) to 1981mN (2kg). It is also
possible to freely set the time for loading and load dwell time. Now your
desire for absolute control over the indentation size in vickers hardness
testing can be satised. The HM-200 series always oers 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 (IF test: JIS R 1607-1995) 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. (e.g. 1.1mm for 50X objective). The contrast that is
most appropriate for the magnication of the objective can be obtained
by manipulating the variable aperture stop in the illumination unit. This
makes the indentations clearly visible, leading less variation and reducing
the chance of error when measuring the diagonal lengths.
