Duramin-4

Duramin-4 – Manual Micro and Micro/Macro Hardness Tester

Entry-level Vickers hardness tester – optimal repeatability and easy operation

Duramin-4 – Manual Micro and Micro/Macro Hardness Tester

  • Suitable for Vickers, Knoop, and Brinell hardness testing
  • Available in two load ranges:
  • Automatic six-position turret
  • Manual XY-stage and Z-axis
  • Manual indent evaluation via an eyepiece

This entry-level range of microhardness testers primarily targets Vickers testing, but can also be used for Knoop and Brinell testing. The Duramin-4 testers are equipped with a combination of manual and automatic features to ensure easy operation. Duramin-4 is available in two load ranges; 10 gf – 2.0 kgf and 1.0 kgf – 62.5 kgf. 

Benefits

Accuracy and repeatability

Advanced load cell technology ensures that the Duramin-4 conforms to all operating standards, while offering consistent repeatability throughout the entire load range.

Easy operation

The display unit combines a touchscreen with a simple user interface, designed to be easy to use, yet robust enough to withstand the toughest production environment. The hardness evaluation takes place manually via an eyepiece, where the measurement lines are simply positioned around the indent.

Dedicated solution

Duramin-4 is ideal for use as a dedicated Vickers single task tester, both in a laboratory (M1) or more production-focused (M2) environment.

Used in these industries:

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

KEY FEATURES

  • Duramin 4 Manual XYstage

    Manual XY-stage

    Using micrometer spindles, the sample is positioned manually. Simply turning the two spindles ensures that the XY-stage and sample can be positioned precisely under the objective lens.

     
  • Duramin 4 Manual zaxis

    Manual Z-axis

    Sample height is adjusted manually by turning a hand wheel. This positions the XY-stage and sample at the ideal working height.

     
  • Duramin 4 Manual evaluation via eye piece

    Manual evaluation via an eyepiece

    Indent evaluation is carried out via an eyepiece, and hardness value is displayed on the display unit.

     
  • Duramin 4 LED illumination

    LED illumination

    The illumination system is based on LED technology to ensure constant illumination intensity throughout the lifetime of the LED. This eliminates variations in indent evaluation that can be associated with other illumination sources.

     
  • Duramin 4 Fast and easy exchange

    Fast and easy exchange of test methods

    Duramin-4 is available with a six-position automatic turret that facilitates the exchange of up to five indenters and five objective lenses. This eliminates the tedious task of continuously exchanging indenters and objectives lenses, avoiding subsequent calibration and potential human errors.

     
  • Duramin 4 Flexible clamping

    Flexible clamping

    Several holders and clamping devices are available, suitable for both mounted and unmounted samples.

     
  • Duramin 4 Available in two versions 1024x759 px

    Available in two versions

    Duramin-4 is available in a low load, low frame version, which is ideal for laboratory use, and in a high load, high frame version for use in a more production oriented or QC environment.
