Increase capacity

The motorized test head enables easy testing of large and tall samples. The automatic XY-stage eases high volume testing.

Consistency and accuracy

Advanced load cell technology ensures that the Duramin-170 not only conforms to all standards but offers the highest possible degree of accuracy and repeatability throughout the entire load range.

Ideal for Jominy testing

Duramin-170 is suitable for automatic Jominy testing, due to the motorized XY-table and dedicated sample holders.


  • Duramin 170 Stable test height

    Stable test height

    The motorized test head, or V-concept, ensures rigid and stable testing conditions without compromising the testing height capacity. It eliminates spindle effect, and the sample is always at the same height above the floor. This means accurate and reproducible results, regardless of the sample size, as well as improved working comfort.
