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.

Specimen holders

ZHVµ-A with motorized X-Y table

  • Long service life thanks to robust and simple construction
  • Light and stiff design from powder-coated aluminum alloy
  • Base with removable loading device to increase flexibility and reduce costs for specimens with varying diameters and shapes
  • Suitable for all X-Y tables by Indentec
  • Only one pressure point facing up: level alignment of the specimen surface with the indenter and lens, parallel to the X-Y table
  • Mounting possible on a prominent point on the X-Y table

Operation

The holder consists of either two or three parts: a base, a drawer and insert rings. Each base can hold drawers for single or multiple molded or welded specimens. The base is located at a fixed position on the table. The appropriate drawer-ring combination is selected according to the specimen size and the specimen is secured in the drawer. The drawer is then slid into the base. The specimen can now easily be located and testing can take place.
