Affri Motorised Rockwell Hardness Tester – MRS Series

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 hard facing. 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.

Fully motorized and automatic, the test is not affected by operator influences and can easily be used by operators of every level

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.

THE FIRST TEST RESULT IS CORRECT AND ABSOLUTE, saving time and money, thus increasing output and productivity.

CONTROL WITH A TOUCH

MRS-PC hardness tester version with LCD multicolor touchscreen for easy test planning and a clear view of results. The user-friendly software is designed with easy setting parameters for measurement setup, statistics and data storage. Hardness scales can be quickly selected from large and clear tabs. Conversion scales, correction for round samples and calibration off-set are always visible. Results are divided according to tolerances and can be viewed in three different types of graphs. Setup customized personal test cycles. Different operators can select their own program finding the software as they left it.
