Founded in 1943 all UHL products like measurement microscopes, micro-hardness testers , custom systems and even the software are based on the basic idea of modular components. In 2000 UHL took over the complete measuring microscope VMM series from Leica. The low-load microhardness tester VMHT was also taken over from Leica in the year 2005. The company continues to evolve and develop new high precision systems for industry & research

MICRO-HARDNESS TESTERS - VMHT Series

The microhardness testers of the UHL VMHT series provide semi- or fully-automatic low-load Vickers or Knoop hardness testing from 1 gm. 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 motorized turret, an optical focus helper

• Specimen stage with analog micrometer spindles (25 x 25 mm)
• Hand driven focussing axis
• High resolution digital video camera OR electronic measuring eyepiece
• Colour touch-display / LCD keyboard display
• The video image is shown directly on the integrated colour display
• Comfortable and fatigue-proof measurement of the indentation on the video screen.
• Data export via LAN or USB media or serial data export (optional)
