The ZHV30 low-load Vickers hardness tester covers Vickers and Knoop hardness tests to ISO 6507, ISO 4545 and ASTM E 384 in the load range from HV0.2 to HV30. For more sophisticated or for automated applications, PC controlled versions are available as semi or fully automatic systems based on the high definition software (HD). 

Advantages of the ZHV30 hardness tester

• 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.
