Universal Hardness Testing
Universal hardness testers cover more than just one hardness measurement method. They are flexible and can be employed for many applications. Thus they offer excellent value for money if you need more than just one test.
Universal Hardness Tester ZHU2.5/Z2.5
The ZHU2.5/Z2.5 is a versatile all-round hardness tester. Simply mount the hardness measurement head. The hardness measurement head is constructed so that it can be used with all Zwick materials testing machines, and for automation. Equipped with other tools or grips, this modular test system is also suitable for tensile, compression and flexure tests.
testXpert® is also utilized as the test software. A cost-optimised supplement has been developed solely for optical hardness test methods.
Integrated in the hardness measurement head are a digital travel measurement system, a load cell and an interchangeable indenter with measurement transducer.
On the whole the hardness measurement head encompasses all hardness tests with indentation depth measurement, e.g. Universal Hardness HU macro range or Martens hardness HM, Rockwell hardness, ball indentation hardness H, Vickers depth measurement HVT, and Brinell depth measurement HBT.
A supplementary Optic unit is used in conjunction with the hardness measurement head when testing according to Vickers, Knoop or Brinell. This unit consists of a measurement microscope with up to 4 objective lenses and a linear slide unit that permits the position between the measurement microscope and the loading assembly to be changed, thus guaranteeing that a component to be tested does not shift.

Mobile Hardness Testers
Many applications require the hardness tester to be taken to the specimen or where a stationary hardness tester that meets all test standards is too expensive. Portable hardness testers are used quite often in such cases.
Mobile Hardness Tester DynaPOCKET PLUS
The Zwick DynaPOCKET PLUS is a pocket hardness tester for rebound hardness measurements according to ASTM A 956.
The hardness tester works on the rebound principle, where an impact body is propelled to a test surface via spring force. Impact and rebound speeds are both measured contact-free. The hardness value is calculated from these two measured values. The rebound speed and the displayed hardness value increase with the hardness of the test material. The rebound method offers high precision and excellent reproducibility of measurements, thus enhancing process security thanks to increased test reliability.
The Zwick DynaPOCKET is simple to handle. Standard conversion tables for 9 material groups are saved in the tester; the corresponding, suitable one must be selected from these 9. Conversion to the following hardness scales is possible: HL (Leeb), HV (Vickers), HB (Brinell), and HRB (Rockwell B).
The Zwick DynaPOCKET can also run conversions according to DIN 50150 and ASTM E 140 for the material groups low alloy and non-alloyed steel and steel casting.
The rebound hardness test with the Zwick DynaPOCKET is primarily geared for solid steel or casting material test pieces.

Mobile Hardness tester MICRODUR MIC 10
The Zwick MICRODUR MIC 10 is a portable hardness tester and works according to the UCI principle (Ultrasonic Contact Impedance). The UCI method enables rapid and comfortable measurements: apply the probe - read off the test data. The Vickers diamond’s indentation in the material surface is measured electronically and is immediately displayed digitally as a hardness value without requiring optical evaluation using a microscope.
This device is typically used to test large containers and pipelines or for tests on specimens at their locations. The small, handy measurement probes even enable measurements at hard to access locations, e.g. cogged wheels, on the tooth flanks or in the gullet. The positioning is freely selectable.
Mobile Hardness tester MICRODUR MIC 10 datasheet
Mobile Hardness tester Webster Test Tong
The handy, portable Zwick Webster test tongs are easy to handle and produce reproducible results.
A test anvil allows tests on different specimen shapes. The test piece is positioned between the anvil and the casing. The material thickness must be between 0.6 and 8 mm. The test anvil is applied by pressing the tester’s grips, and the indenter is applied via the test spring. A value between 0 and 20 that is proportional to the indentation depth is displayed. The Rockwell value can be read off from the diagram supplied with the hardness tester. This value can be converted to other hardness with the help of conversion tables.
Mobile Hardness tester Webster Test Tong datasheet
Mobile Hardness Tester Sclerograph
The handy, portable Zwick Sclerograph hardness tester is based on the rebound method and is suitable for determining the hardness of steel, non-ferrous metals, and rubber.
The Sclerograph is placed vertically on the test piece. The drop rod is pulled upwards beyond the locking device. Pushing the release lever causes the drop rod to fall downwards. The ball hits the test piece and rebounds. The specially developed arrest device catches the drop rod when at its highest position after rebound.
After the rebound height has been read off and after comparing it to the comparison table supplied, the values can be determined according to Shore D, Rockwell C and B, and Brinell. The accuracy is ± 2 Rockwell units.
