Duramin-650 is the universal tester suited for laboratory use. Each model in the range has a motorized test head and turret, and is available either with a fixed anvil or with a motorized XY-stage and overview camera, primarily suitable for high volume testing. Duramin-650 is available in three load ranges.
Due to the wide test load ranges possible, the Duramin-650 is suitable for many different applications that previously needed several individual macro indentation hardness testers.
Based on load cell technology, the Duramin-650 conforms to all standards while offering excellent accuracy and repeatability throughout the entire load range.
Duramin-650 is optionally available with a motorized XY-stage for fully automatic testing of test series.
The motorized test head, or V-concept, ensures rigid testing conditions without compromising on the testing height capacity. The sample remains at the same height to secure accurate and reproducible results, regardless of the sample size and weight.
The Duramin-650 automatically adjusts to the correct working height by moving the measurement turret down until it touches the sample's surface.
The machine automatically stops during a collision or any unexpected vibration or movements. This protects the indenters and lenses from being damaged and also provides optimal operator safety.
Duramin-650 is available with a six-position automatic turret that facilitates the exchange of up to three indenters and three objective lenses. The exchange of indenter and lens runs fully automatically, hereby avoiding misalignment and operator errors.
The optional overview camera makes it easy to position the test point series across the sample and execute the test series with a few mouse clicks.
Duramin-650 is also available with a built-in test point editor to define and set up measurement lines for fully automatic testing.
Application specific software modules are available for a variety of needs: a weld measurement module, surface mapping, edge detection, and a Kc fracture toughness calculator.
Through eliminating the common overshoot and undershoot from dead weight systems, load cell technology ensures the highest degree of accuracy and repeatability during load application. The absence of mechanical weights not only eliminates friction problems but also makes the equipment less sensitive to misalignment caused by vibrations. Combined with a motorized turret, the entire measurement cycle of loading, indenting, unloading, focusing, and evaluating is carried out extremely quickly.
All Duramin-650 models come with a motorised test head, automatic illumination adjustment, auto focus and automatic image evaluation. The maximum sample height is 300 mm, with a throat depth of 220 mm. Duramin-650 is operated via a 15” colour LCD touch screen control.
Duramin-650 M range come with a fixed test anvil (Ø80 mm dia.) and a motorised 6-position turret.
The Duramin-650 AC range come with a test point editor, motorised XY-stage (size 390 x 262 mm, stroke 250 x 160 mm) and a motorised 8-position turret, including laser pointer and overview camera.
Objective lenses and indenters are ordered separately.
