Duramin-100 range combines both a micro and universal tester. The top model covers a wide load range from 10.0 gf to 250 kgf, and includes a motorized XY-stage, motorized test head, overview camera, laser guide, and eight-position turret. Duramin-100 is available in three 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 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.

Used in these industries:

  • Automotive
  • Aerospace
  • Electronics
  • Manufacturing
  • Education & Research


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.


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 Unprecedented adaptability

Unprecedented adaptability

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


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.


Duramin 100 Relevant software

Relevant software

Application-specific software modules are available, including a weld measurement module, surface mapping, edge detection, and a Kc fracture toughness calculator.


Duramin 100 Customise test reports 1024x759 px

Customize test reports

Duramin-100 is available with a built-in test point editor to define and set up measurement lines for fully automatic testing. This includes both straight lines and zig-zag lines, and enables customized test reports to be easily generated and printed.
