DuraScan: Fully Automatic Hardness Tester from Struers

Struers’ new fully automatic hardness tester is the DuraScan. The DuraScan has an automatic test cycle capable of handling load selection, indentation, focusing and hardness assessments. It is designed with state-of-the-art load control that is integrated with load cell and dead weight technology, thus ensuring superior precision and repeatability, which is essential in the nanotechnology domain. Its test load range extends from 0.098N (10gf) to 98.1N (10kgf).

Struers’ DuraScan is equipped with a high-resolution CCD camera and a second CCD camera that functions as an overview camera to enable easy positioning and choosing of starting points and test series.

Struers has also provided a template management with the DuraScan that enables simple setting up and implementation of test, and LED technology to provide stable illumination intensity.
