Excellence in Materials <strong>Testing</strong><br />
Struers hardness testers are focused on providing customers a high degree of repeatability<br />
and reproducibility, factors essential in quality control. Easy-operation features such as automated<br />
test procedures and integrated image analysis help personnel to work faster and more<br />
accurately. For most applications Struers offers solutions that can suit your particular needs.<br />
<strong>Hardness</strong> <strong>Testing</strong><br />
<strong>Hardness</strong> testing is universally used in quality control, research and development. The main<br />
purpose of the hardness test is to determine the suitability of a material, or the particular heat<br />
treatment to which the material has been subjected. Many factors can influence the hardness<br />
measured and, apart from the material itself, can be related to the equipment or the measurement.<br />
The STRuERS Duramin hardness testers are state-of-the-art software-controlled devices which enable<br />
micro- and macro hardness tests to be performed rapidly, accurately and reliably. The hardness testers are<br />
equipped with a unique test load range, covering many applications. Struers Duramin hardness<br />
testers are particularly suitable for industrial research and in quality control. The EMCO-TEST line of the<br />
Struers hardness testers range from portable and bench-top hardness testers to large custom-made<br />
in-line systems. These hardness testers are particularly suitable for industrial quality control.

MICRO HARDNESS TESTERS<br />
DuraScan is a state-of-the-art hardness testing system with unique test load range from<br />
10 gf to 10 kgf, covering many applications. Fully automatic test cycles and hardness evaluation<br />
ensure the highest repeatability and reproducibility. The optional overview camera makes<br />
it easy to select starting points and test series with just a few mouse clicks. Intuitive software<br />
following the natural workflow of performing the hardness test procedure. Ideal for CHD<br />
measurements and testing of welds. Available in semi- and fully automatic versions.<br />

Automatic turret for DuraScan<br />
The DuraScan is controlled by the ecos Workflow software for fully automatic measuring<br />
and hardness progression evaluation. With built-in statistics functions and report editor.<br />
The software is workflow oriented meaning that the layout of the software follows the natural<br />
workflow of the software, with functions only available when needed. The result is an<br />
extremely intuitive and user-friendly software requiring a minimum of training.<br />

The hardness testing workflow – step by step<br />
Vertical test head<br />
The DuraScan hardness testers are based<br />
on an asymmetric and compact design. On<br />
the automatic versions the stage is only<br />
moveable in the x-direction whereas the test<br />
head is moveable in the y- and z-directions.<br />
The advantage of this patented concept<br />
is increased testing speed and very high<br />
positioning accuracy.

Overview camera<br />
On DuraScan with the overview camera option you have the possibility<br />
of easily position and execute your test series with just a few<br />
mouse clicks. You can save single and multiple test point series as<br />
templates and easily position them across your sample.<br />
This feature is very helpful if you are performing repetitive or high<br />
volume CHD-measurements or just want easy set-up and execution<br />
of your test series.<br />
Welds<br />
The overview camera allowing you<br />
to view the entire sample and place<br />
test points via mouse clicks<br />
When material is welded together, you often want to check the quality<br />
of the welded sample by performing hardness measurements at<br />
various places across your sample. Typically, a line of indentations<br />
is made a few mm parallelly to the sample edge across the sample<br />
surface. In particular the hardness around the heat affected zone<br />
(HAZ) is of interest, as too high hardnesses might incur risks to<br />
the strength of the weld.<br />
Base material<br />
Heat affected zone<br />
As your test series usually are performed over a large area or long<br />
distance, they can be difficult to carry out under a normal objective<br />
lens. With a fully automatic DuraScan hardness tester with the<br />
overview camera option you have the possibility to easily position<br />
and execute your test series - with just a few mouse clicks.<br />
You can also save your test point patterns<br />
as templates for future use. All<br />
this will save you valuable time during<br />
both setup and execution of the test<br />
series.<br />

the overview camera on DuraScan<br />

Case <strong>Hardness</strong> Depth Measurements<br />
(CHD-Measurements)<br />
CHD-measurements are performed in order to evaluate the hardness<br />
depth of surface hardened materials. The output of the measurement<br />
is typically a value in mm or other suitable unit that indicates<br />
the distance from the sample surface to a specific pre-determined<br />
hardness value (the hardness limit). The value is then compared<br />
with pre-determined standards. The exact procedure of the measurement<br />
depends on the utilised surface hardening process as well as<br />
the sample type. Usually a series of indentations is performed in a<br />
particular pattern, propagating from the sample surface to the centre<br />
of the sample. The hardness values are then plotted in a graph and<br />
you can then read out at which distance from the sample surface<br />
you have reached a certain hardness value.<br />
Plot showing CHD (Eht) value<br />
Illumination system<br />
The increasing size of the indentations<br />
indicates decreasing hardness<br />
of material.<br />
Together will all newer Struers hardness testers, the DuraScan, is<br />
based on an LED illumination system. In contrast to traditional halogen<br />
light bulb systems a LED system produces a constant illumination<br />
intensity throughout the day and over its lifetime. Additionally<br />
the DuraScan automatic adjusts the illumination to fit the actual<br />
sample surface, producing uniform testing<br />
conditions for all sample types, thus not<br />
influencing the calibration. These are just<br />
additional factors influencing the reliability of<br />
your hardness test – and just another reason<br />
to choose a Struers hardness tester.
