Details

ONE BUTTON MEASUREMENT

     

CLOSED LOOP TECHNOLOGY (PAT. AFFRI)

Just press one button and the hardness tester's head moves down to make contact with the sample's surface, locking it. The hardness test cycle will automatically begin in automatic succession without breaching a phase. Within seconds results appear.

     

Load forces are applied through load cells and controlled in "Closed Loop" with a frequency of 1 khz, assuring perfect linearity in every range. Results are not affected by any structural deflection, misalignment or vibration.

         

INDENTER STROKE

     

MREPEATABILITY & REPRODUCIBILITY

Automatic movement with automatic stop when contact is made with samples. Total of 700 mm of motorized vertical stroke. The approach of the head moving to the piece as opposed to the piece moving to the head allows for more accurate, stable and safe measurements.

     

Secure contact with the specimen is always maintained, 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.

         

 LARGE BASE

     

 SOFTWARE

The 3332 MRS’s wide work table base is capable of bearing masses beyond 1000 kg which allows for steady hardness measurements on bulky or irregular pieces. It also offers a comfortable working base for small pieces.       The pre-installed software controls the whole instrument during the entire cycle avoiding operator errors. Powerful analysis system with easy and fast test settings, live statistics and graph. Data and test sessions storage.
