WK Series
Model: WK
Hardness testers with built-in probe and microscope for automatic measurements across Rockwell, Brinell HBWT and Vickers indentation.

About the WK Series
WK is an accessory applicable to each hardness tester to transform them into universal hardness testers for Brinell, Vickers and Rockwell measurements. Suitable to measure any kind of component thanks to the automatic scanning of indentation by optic probe and the direct view of result on the LCD touch-screen. Data report can be created and exported.
THE HEART OF AFFRI SYSTEM Affri System assures easy and fast measurements in any conditions. The hardness tester applies preload and load in automatic succession; within seconds the result appears.
WK accessory allows to make automatic tests for Brinell and Vickers scale. The automatic focus, the zoom, real magnification 25X and 50x give you perfect measurements. Check results and data on the touch-screen and export them through Windows multi language software.

Automatic motorized hardness testers
250 DRM is a fast and really easy bench hardness testers with high accuracy standards. To perform the test just act on the elevating screw and bring the sample to make contact with the indenter, then push the start button activating preloading and loading in automatic succession; within seconds results appear. Load forces are electronically applied throug load cells which eliminates problems associated with dead weight systems on traditional testers. It is not affected by vibration and it doesn’t need to be leveled.

Semi-automatic hardness testers
206 EX is a fast and really easy bench hardness testers with high accuracy standards. To perform the test just act on the elevating screw and bring the sample to make contact with the indenter, then pull the lever activating preloading and loading in automatic succession; within seconds results appear. Load forces are applied through two dynamometric load cells which eliminates problems associated with dead weight systems on traditional testers. It is not affected by vibration and it doesn’t need to be leveled.
