Affri Rockwell Hardness Testers MRS Series

The MRS Series.

hardness testers Each machine is robust and very easy to use and produces a fast and accurate hardness measurement

Load forces: from 1 to 250 kgf (From 9.807 to 2452 N)
Rockwell ISO 6508 / ASTM E-18: HRA - HRB - HRC - HRD - HRF - HRG - HRL - HRM - HRR  /  HRN - HRT
Brinell HBWT ISO 6506 / ASTM E-10: HB 30 - HB 10 - HB 5 - HB 2.5 MPa (F/D2)
Vickers ISO 6507 / ASTM E-384 (Indentation only): HV1 - HV3 - HV5 - HV10 - HV15 - HV20 - HV30 - HV50 - HV100
Automatic hardness testers for Rockwell, Superficial Rockwell, Brinell, Vickers and Shore test methods in compliance with ASTM and ISO hardness standards. MRS Series are top level bench hardness testers for tough or lab applications. Fully motorized for fully automatic test cycles. Absolute accuracy (better than 0.5 %) in every condition. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). Exact hardness result on the first test and R&R data at the top of his class. Digital durometers with LCD screen, user friendly interface, real time statistics, graphs and large archive storage. 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.

Each machine has easy operations

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.

When testing unstable samples or deflecting parts, the AFFRI System will follow the sample without losing contact thanks to its 50 mm stroke for indenter and clamping hood. Easy and fast hardness measurements on pieces with different thicknesses without acting on tester head or elevating screw.

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.

Accurate measurements on the first test, even in extreme conditions, eliminate the need for repeated tests. The R&R data is at the top of its class.

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.

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.
