Rockwell hardness testers MRS Series are top level bench instruments, fully motorized for fully automatic hardness test cycles. In compliance with ASTM and ISO hardness standards with absolute accuracy (better than 0.5 %) in every condition. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). Hardness testing on all metals: iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing. Hard and soft plastics.
ONE BUTTON MEASUREMENTS
Automatic preloading, loading and measurements. AFFRI System hardness testers achieve the highest level of depth accuracy and measurement resolution available for Rockwell tests. Thanks to the AFFRI System, the real indentation measurement is guaranteed without any external interference in any condition.
- Auto-contact with the specimen
- Auto-clamping and activation of the reference surface point
- Automatic preloading and loading
- Auto-measure
- Automatic return stroke at programmed distance
The entire test cycle is complete and the result immediately appears on the display.
AUTO-COMPENSATION OF ALL DEFLECTIONS
Rockwell hardness testers MRS Serie are equipped with an independent stroke of 50 mm which moves the indenter and the clamping hood. This is a stand-alone extra stroke that works in addition to the head movement. During the test, the system generates a constant pressure when the specimen is clamped.
When testing unstable samples or deflective parts, the measuring head follows the sample without losing contact. The top surface referencing design minimizes errors caused by problems associated with dirt or scale. This reduces sample preparation time and increases both accuracy and speed.
- Hardness test on unstable samples
- Auto-compensation of oil or dust under the specimen
- Controlled depth measure even if the sample moves downward
- Auto-alarm and stop if the sample moves away
- Auto compensation of any structural flection
CLOSED LOOP INVENTED BY AFFRI
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.
The Affri® System assures the highest reliability and accuracy in any measuring condition. Measures are always independent of any external condition, whether physical, mechanical or human. Test R & R of Repeatability and Reproducibility brings the Affri® System at the top in industrial innovations.
MAIN FEATURES
THE MOTORIZATION
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.
THE CLAMPING (PAT. AFFRI)
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.
HARD BASE
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.
