Duramin-4
Entry-level Vickers hardness tester – optimal repeatability and easy operation
Duramin-4 – Manual Micro and Micro/Macro Hardness Tester
Methods: Vickers, Knoop and Brinell hardness testing
Load ranges: 10 gf-2 kgf, 1-62.5 kgf
Manual micro and micro/macro hardness tester
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.
How does Duramin 4 support your Hardness Testing
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.
Accuracy and repeatability
Easy operation
Dedicated solution
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.
Manual XY-stage
Sample height is adjusted manually by turning a hand wheel. This positions the XY-stage and sample at the ideal working height.
Manual Z-axis
Indent evaluation is carried out via an eyepiece, and hardness value is displayed on the display unit.
Manual evaluation via an eyepiece
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.
LED illumination
Duramin-4 is available with a six-position automatic turret that facilitates the exchange of up to five indenters and four objective lenses. This eliminates the tedious task of continuously exchanging indenters and objectives lenses, avoiding subsequent calibration and potential human errors.
Fast and easy exchange of test methods
Several holders and clamping devices are available, suitable for both mounted and unmounted samples.
Flexible clamping
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.
Available in two versions
