Duramin-100 range combines both a micro and universal tester. The top model covers a wide load range from 10 gf to 250 kgf, and includes a motorised XY-stage, motorised test head, overview camera, laser guide and 8-position turret. Duramin-100 is available in 3 load ranges and is suitable for Vickers, Brinell and Rockwell hardness testing. Add-on modules include Kc fracture measurements, mapping and weld measurements.


Wide load range

Save time and money with Duramin-100’s unique test load range. Covering a range from 10 gf to 250 kgf, Duramin-100 can be used for many different applications that usually required both a micro and a macro indentation hardness tester.

Reliability with load-cell technology

Duramin-100 conforms to all standards while offering the highest possible degree of accuracy and repeatability throughout its entire load range. This is due to advanced load-cell technology.

Exceptional overview

The optional dual monitor solution enables both the general measurement data and macro overview image to be shown simultaneously on two separate monitors. This saves time when setting up and executing advanced test series.

Key features

  • Duramin 100 Motorised test head

    Motorised test head (V-concept)

    The V-concept ensures rigid and stable testing conditions without compromising the testing height capacity. It eliminates the spindle effect and ensures that the sample is always at the same height above the floor. This secures accurate and reproducible results regardless of the sample size. It also improves working comfort for operators.

  • Duramin 100 Automatic height adjustment

    Automatic height adjustment

    The Duramin-100 quickly adjusts to the correct working height by moving the measurement turret down until it touches the samples surface. This enables faster and easier set-up of hardness tests.

    Automatic height adjustment
  • Duramin 100 Simple test execution

    Simple test execution

    The standard overview camera enables the test point series to be positioned quickly and easily across the sample. The test series can then be executed with just a few mouse clicks.

    Simple test execution
  • Duramin 100 Automatic exchange of indenter and lens

    Automatic exchange of indenter and lens

    Duramin-100 is available with an eight-position automatic turret that facilitates the exchange of up to six indenters and five objective lenses. Regardless of model, the exchange of indenter and lens runs fully automatically.

  • Duramin 100 Unprecedented adaptability

    Unprecedented adaptability

    The integrated zoom function reduces the number of objective lenses required and increases the adaptability of the machine.

    Unprecedented adaptability
  • Duramin 100 Avoid indenter and lens damage

    Avoid indenter and lens damage

    The machine automatically stops operation in the event of a collision or any unexpected vibration or movement. This prevents indenters and lenses from being damaged and secures optimal operator safety.
