Wide load range

Save time and money with Duramin-100’s unique test load range. Covering a range from 50 gf to 250 kgf, Duramin-100 can be used for many different applications that usually require 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.


  • Duramin 100 Motorised test head

    Motorized 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 sample's surface. This enables faster and easier setup 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.

  • 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 the model, the exchange of indenter and lens runs fully automatically.

  • 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.
