The microhardness testers of the UHL VMHT series provide semi- or fully-automatic low-load Vickers or Knoop hardness testing from 1 g to 2 kg.
Using brilliant Leica optics and a high valuable load mechanism with fixed weights to apply the test force, repeatable and long time stable results are achieved.
Even the basic model is equipped with a user friendly motrized turret, an optical focus helper and motorized load selection.
VMH-002VD
(manual)
Model similar to VMH-002V with digital micrometer spindles
• direct creation of hardness depth patterns by graphical display and video image
• visual checkup of the minimum distance between edge and indentations according to the DIN EN ISO 6507/1-2 standard
• optional automatic indentation measurement (VMH-002VAD)
VMH-002VM
Model similar to VMH-002VD but with motorized specimen stage 50 x 50 mm and stepper motion controller with joystick
• automatic positioning of the specimen
during hardness depth measurement
• the operator can prepare further specimen
while the indentations are done automatically
• optional automatic indentation measurement (VMH-002VAM)
VMH-I03
(semi-automatic)
Hand driven video microhardness tester with image processing
• specimen stage with analog or digital micrometer spindles (25 x 25 mm)
• automatic indentation measurement (avoids user influence)
• flexible definition of hardness depth patterns with lists of steps or X/Y patterns
