A standardized portable hardness tester
Unbelievable performance never seen before with the Affri Hardness Tester RS-MAG.
A conventional hardness tester including conformance to any standard is available, as a portable system for onsite testing when test pieces are too large or too heavy that a  bench hardness tester is not capable to accommodate it. The AFFRI magnetic portable hardness tester solves all such type of necessities.
AFFRI’ state of the art technology permits different tests at different load forces.
The load cell inside has no impact force, while the Affri vertical movement permits a fully automatic test cycle.
It conforms to all Rockwell, Brinell, hardness standard methods.
The standardized high pressure on the indenter creates depth indentations on the surface. Thus eliminating the need for special surface preparation; a simple grinding of 180  grit on a small area just where the indenter will indent.

Vertical sliding indenter 50mm range action assures easy test at different distance between test surface and indenter

a single test force between 60 - 100 - 150 Kp (187,5  kg for Brinell)
RS-MAG-D2  :
selectable test forces 60 - 100 - 150 Kp (187,5 kg at request)
RS MAG-D3  :
a single test force between 15 - 30 - 45 Kp
RS MAG-D4  :
selectable test forces 15 - 30 - 45 Kp - Digital direct readout scale Rockwell and Brinell units

Follow the profile of test piece
The Affri vertical stroke system of the measuring head, 50 mm (2”) follows the profile of test sample, it assures a very accurate and
absolute measurement even when sample retracts during test cycle. (Original Affri Patented System)
It has been designed and studied by AFFRI engineers which create the state of the art, in hardness test systems for over 55 years
The AFFRI -RS MAG is completely uninfluenced by direction so that it is operative up to 360° positioning and is not affected by any external source of vibration; It does not need to be leveled.
It is absolutely fantastic difficult to believe.
On digital model the internal battery assures 20 hours operation use.
The state of the art Affri system protects the indenter by accidental shock before and during test, thus increasing the life of indenter especially for diamond cone 120° Rockwell C test.
The Affri RS MAG can be clamped on flat or round surfaces.
The automatic vertical movement of the indenter including clamping system takes contact with the test surface automatically so that need pull one start lever only to perform the entire test cycle.

Easy to operate
It is so easy to manipulate, pull one single start lever and the measure will appear in a few seconds; there is no motor inside but at same time it’s a totally automatic system.
It is so simple and easy to use that there is no need for any particular preparation by the operator. Identify the test area and place the hardness tester on the test sample, then lock the magnetic lever, the tester will strongly adhere to the test piece and remain clamped for the entire test cycle: you pull the single start lever for few seconds and the head moves down dynamically until it makes contact with test surface and generates the measure cycle.
In 4 second the result will appear on the display scale or dial gauge.
