Following the Rebound Leeb's principle, Leeb Portable Hardness Tester - Hartip 3000 - Portable Hardness Tester - offers an excellent price/quality ratio in our range of rebound-type portable hardness testers. These models are efficiently and fully supported by our in-house technical & service department.
Rebound-type hardness testers cover a broad range of applications in industry and supply the required test results, in almost every application, where fixed hardness testers can not be used. These portable hardness testers conform to ASTM A956 standard. The minimum requirements that have to be met in order to achieve accuracy with Leeb Portable Hardness Tester - Hartip 3000 - Portable Hardness Tester, are minimum thickness of 3/8" (10mm) and weight of 11lb (5kg) for the samples. Rebound-type hardness testers are suitable for:
Operation of the Leeb Portable Hardness Tester - Hartip 3000 - Portable Hardness Tester - is easy and test results can be obtained in just seconds. All you have to do is to load and lock the impact body by pressing down the loading tube, hold the support firmly against the test surface and push the button to release impact body.
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.
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.

|Application:||Special Impact Devices:|
|Universal standard impact device, will handle the majority of hardness testing applications||
|Very short impact device for confined areas i.e. inside bores or holes for internal measurements. Conforms to the D measuring range||
|Very narrow contact area with a set backed measurement coil. This device is used to measure hardness in grooves and recessed surfaces||
|A reduced impact energy impact device (25% of D) for measuring the hardness of surface hardened components, coatings, thin wall or impact sensitive components. Applies a small indentation.||
|This device has an enlarged test tip, and an increased impact energy range (approx. 9 times higher than D). Can be used on lower quality finishes for measuring hardness in the Brinell range only (max. 650 HB). Designed to be used with heavy components such as heavy castings and forgings.||
|Uses a synthetic diamond cast tip (approx. 5000 HV) for measuring extremely high hardness properties. This would include materials having a hardness in excess of 50HRC/650HV, i.e. tool steels with high carbide inclusion content. For measuring Very hard surfaces up to 1200 HV.||
|Extremely confined spaces, the base of grooves, and special components such as gear wheels, etc.||
