ZHV30 Vickers hardness tester

The ZHV30 low-load Vickers hardness tester covers Vickers and Knoop hardness tests to ISO 6507, ISO 4545 and ASTM E384 in the test-load range from HV0.2 to HV30. For wider-ranging or automated applications, PC-controlled versions are available as semi or fully automatic systems based on the high-definition software (HD).

Overview of key advantages

  • Load levels with motorized load change: 0.2, 0.5, 1, 3, 5, 10, 30 (in kgf).
  • Motorized turret for changing between indenter and lenses enables automatic test sequence.
  • Turret for four lenses and one indenter eliminates risk of confusion.
  • Load application via dead-weights guarantees test-force repeatability and long-term stability.
  • Freely adjustable dwell times from 5 to 60 seconds.
  • Individual lighting setting for each lens.

Additional advantages of HD software

  • Software-controlled versions for semi to fully automatic hardness testing systems offer the following additional advantages.
  • Operation and control of hardness tester via high-definition software.
  • 1.3-megapixel USB camera.
  • Scan function (stitching) with 2.5x lens provides high-resolution overview image of specimen surface.
  • Fast, easy positioning of test points in overview image.
  • Automatic indentation measurement with lighting and shadow correction eliminates operator influence during determination of the hardness value.
  • Motorized X-Y table with 100 mm x 60 mm travel.
  • Automatic hardness traverse testing.
