MRS Series

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.

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

• 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

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.

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.

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.

L.I.S.A – Laser Indicator System Affri (Patented)

Exclusive application which allows ultra-precise test positioning. The laser pointing system helps to define the indentation area before the contact between the indenter and the specimen. Reach extreme points with lack of illumination, edges of gear’s teeth or sides of cutting tools and blades. (This application is optional)

Sample Illumination By Led

Adjustable LED light source for a clear view of the test zone on any surface or specimen shape. Illuminate extreme points where lighting is low like sample holes and dark layers. The adjustable arm of the light can be bent in any direction allowing illumination outside of the testing area. (LED light is optional)
