Measuring Method:

The Leeb hardness number is the quotient of the impact body's rebound velocity divided by its impact velocity. An impact body with a spherical test tip made of tungsten carbide is propelled against the test surface by a spring and then rebounds. When the permanent magnet inside the impact body passes through a coil, it induces an electric voltage, which is proportional to its velocity.

Specifications for Leeb Portable Hardness Tester - Hartip 3000 - Portable Hardness Tester:

Limitations:

For D, DL, DC, D+15, and E Impact Devices: a Minimum thickness of 10mm (3/8 inch) is required. The sample weight is required to be over 5kg (11 lbs), however for samples weighing less than (5 kg) 11lbs, you can couple the sample to a solid support weighing over 5kg (11lbs) to achieve accuracy. The maximum roughness of surface finish is 2µ Ra.

For G Impact Device: a Minimum thickness of 10mm is required. The sample weight should be over 15 kg, however for weights less than 15kg, you can use the sample coupling method. The Maximum Roughness should be 7µ Ra.

For C Impact Device: a Minimum thickness of 1mm is required. The sample weight should be over 1.5 kg, however for weights less than 1.5 kg you can couple the sample to a solid support. The Maximum Roughness requirement is 0.5 µ Ra.

Standard Kit includes:
