Details

ONE BUTTON FOR MEASUREMENT

     

CINDENTER & CLAMPING HOOK STROKE

Just press one button and the hardness tester's head moves down to make contact with the sample's surface, clamps the piece, applies the force, makes the indentation and goes back upwards. Within seconds results appear. For Vickers and Knoop indentations, just place the camera in reading position and the indent is automatically measured.

     

When testing unstable samples or deflective parts, the AFFRI System will follow the sample without loosing contact thank's to its 50 mm stroke for indenter and clamping hood. Easy and fast hardness measurements on pieces with different thicknesses without acting on tester head or elevating screw.

         

CLOSED LOOP TECHNOLOGY (PAT. AFFRI)

     

REPEATABILITY & REPRODUCIBILITY

Sliding table 100x100 mm with 25 x 25 mm X/Y stroke and 10 μm step, for an easy and accurate positioning of the sample.

     

Secure contact with the specimen is always mantained, even in the unlikely event of any specimen movement during the operation cycle. The clamping system assures perfect stability of any test piece throughout the test cycle, even if it's oiled, rusty or dirty.

         

AUTO INDENTATON READING

     

SOFTWARE

Thanks to the CCD high definition camera and to the AFFRI software, the indent reading process is automatic and assures absolute accuracy even if the samples surface isn't perfect. From perfectly polished to rough and etched samples, the indentation auto-detection allows measurements on a variety of sample surfaces.       AFFRI analyse system with fast and easy scales selection and test settings. Results and live statistics. Storage of data and test sessions.
