In the laboratory of Istanbul Dokum, for all productions, chemical analysis, mechanical yield – tensile – elongation tests, and when required hardness tests, UT, MT and MPI tests are provided.

Our measuring microscopes accommodate highquality optics in a robust lightmetal body. They are universally applicable, e.g. for testing hardness, evaluating Brinell and Vickers hardness, in graphics or for noncontact measurement of small parts and small distances. Our 20x/7 mm, 30x/5 mm, 40x/4 mm, 60x/2 mm and 100x/1 mm measuring microscopes feature batteryoperated LED illumination as standard.

The new versions of our hardness testing applications for VMH-002 to VMH-I04 are supporting now the usage of editable conversion tables (Standard ASTM E 140: HV, HK, HRC 150, HRD 100, HRA 60, HR 45-N, HR 30-N, HR 15-N). The curvature / radius of the specimen surface can be considered now, by using a radius correction table accodring to ISO 6507-2.

The microhardness testers of the UHL VMHT series provide semi- or fully-automatic low-load Vickers or Knoop hardness testing from 1 g to 2 kg. Using brilliant Leica optics and a high valuable load mechanism with fixed weights to apply the test force, repeatable and long time stable results are achieved. Even the basic model is equipped with a user friendly motrized turret, an optical focus helper and motorized load selection.

Combining the bestThe ZHU250CL hardness tester employs the latest technology, with closed-loop control for test load application. The modern system for test load application (closed loop) stands out because of its precision. Accuracy exceeds the requirements of all relevant ISO and ASTM standards. Range of Hardness Applications: - Vickers according to ISO 6507, ASTM E384 - Knoop according to ISO 4545, ASTM E384 - Rockwell according to ISO 6508, ASTM E18 - Brinell according to IS0 6506, ASTM E10 Features: • Extremely wide test force range of 0.5 kg to 250 kg • Unique “4-plus-4” turret able to carry up to 4 lenses and up to 4 indenters simultaneously. The turret is also designed to allow testing in hard to reach positions by using a unique vertical rotation mechanism. • Variable dwell times 5-60 seconds • Ability to vary indenter approach velocity • Rockwell depth measured by the market leading Indentec transducer capable of a measuring resolution of 0.1 Rockwell point

The ZHU/Z2.5 is the most versatile and flexible hardness testing machine in the world, it has a zwickiLine testing machine with a hardness measurement head which contains a digital travel-measuring system and an exchangeable indenter with sensor foot. It can be used with all ZwickRoell Materials testing machines and in automated applications. All indentation depth measurement method hardness tests, including Martens hardness HM, Rockwell hardness, and ball indentation hardness can be performed. Vickers depth measurement HVT, Brinell depth measurement HBT, and Knoop tests can be performed with an optical unit accessory attached to the head. This unit contains a measuring microscope and a linear displacement component, which allows the microscope and load unit to exchange positions without the need to move any components under test.

The low load Vickers hardness tester ZHV30 conducts Knoop and Vickers hardness tests in accordance to the ISO6507, ISO4545 & ASTM E 384.The test load range is between HV0.2 and HV30. With an an automatic 5 position turret for an indenter it consists of maximum of 4 lenses facilitating the change and selection through the menu buttons. The magnifications of 25x to 500x helps in covering various applications. Integrated microscope and front panel display facilitates quick and easy hardness testing. The dwell times may be easily configured in electronics and test cycle is automatic. The load change is automatic and the test load is selected through the operating panel. Illumination intensity for each magnification lens can be stored individually. PC controlled versions,based on a High Definition software, which are semi automated or fully automated are also available for automated and sophisticated applications.

The Zwick analog shore hardness tester is a testing device with a pointer. Due to its pointer, this tester can be used to measure value that is shown after the test in hard-to-access locations. Also, it can work in tests such as soft rubber, elastometers and natural rubber to Shore A. For tough materials, these includes harder elastomers, plastics and rigid thermoplastics to Shore D. This tool can work with either material that has different hardness rating coming from shore A up to Shore D. Plus, this test device have load weight and control unit which can be easily accessible.

The ZHU 250 is ideally designed to promote an excellent quality performance and functionality. It is built with an attractive and sophisticated structure used for a very simple and easy operation, direct-viewing and more.
