Vickers Hardness Tester - Load Range 0.00025-62.5kgf

The pioneering standard load range of the DuraScan G5 from 10 gf to 62.5 kgf expands the application range of the hardness tester enormously. This can be extended optionally to the range from 0.25 gf to 62.5 kgf – even subsequently at any time! The force is thereby continuously and precisely monitored electronically using a series of electronic force measuring sensors.

The base for all machines of the DuraScan G5 series is a sturdy baseplate of high-quality granite. In combination with the legs developed by EMCO-TEST with integrated damping elements, it insulates the hardness tester against vibrations at the installation location. The frame construction of cast aluminium calculated using FEM and the highprecision linear guides guarantee precision and freedom from maintenance.

The DuraScan 80 G5 variant has a significantly larger test area. With the 300 mm travel distance of its X-axis, up to 12 specimens in two specimen holders can be positioned and processed at the same time. The useful working area is increased to 300 x 150 mm. The base for this device is a solid granite slab measuring 700 x 450 mm.

The 10 Mpix camera employed in all devices of the DuraScan G5 series sets new standards in image quality. The intelligent use of the high-resolution camera chip allows a 3x zoom without having to accept any loss in quality due to interpolation. This innovative solution allows a broad range of applications to be covered with a small number of lenses. In order to make full use of this potential, the DuraScan G5 uses only lenses that offer maximum optical resolution. The proven fully automatic evaluation reliably regulates the brightness of the image and automatically evaluates the indentation.

Fast height adjustment

The proven height adjustment of the test head allows a constant and ergonomic working height. The rapid traverse helps to significantly accelerate the adjustment to different test specimen heights. The scanning function ensures automatic positioning of the test head to the perfect working distance – the camera image is immediately sharp.

XY table or test anvil

The basic version provides a plane anvil with all the requirements for quick and easy individual tests. The DuraScan 20 sees the series expanded to include a manual XY-cross slide enabling reliable series measurement. Optional digital spindles are also available.

Overview camera (DuraScan 70 G5, 80 G5)

The tried and trusted overview camera ensures the perfect overview, regardless of how complicated the test procedure or the number of test points and test rows. The combination of a macro lens and a superior quality lens facilitates view ranges of 60 μm to 62 mm. This unique technology allows an overall picture of the test subject (50 x 62 mm) and clearly displays every test run. A significant simplification of the task is provided by the addition of grid, support and reference lines including a display of the possibilities for moving edges. Furthermore, the picture can also be saved in the report.
