Rockwell hardness testers MRS Serie, for automatic use

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.

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

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.

EXTRA FEATURES

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)
