Hardness Tester uses a proven, dynamic testing principle.  An impact body with a hard test time is propelled by spring force against the test piece.  Surface deformation takes place when the impact body hits the test surface, which results in a loss of kinetic energy.  This kinetic energy loss is detected by a comparison of velocities (VA – impact velocity, and VB – rebound velocity) when the impact body is at precisely 1mm distance from the surface for both the impact and rebound phase of the test.

Advantages

• Wide measuring range – can measure Leeb Hardness of all metallic materials.
• Large screen shows all functions and parameters.
• Can test at any angle, including upside down. Automatic compensation for impact direction.
• Converts to all common hardness scales (HV, HB, HRC, HRB, HS, HL)
• Stores readings to memory, can calculate average readings based on pre-set number of test.

Disadvantages
