Rockwell hardness testers RSD measuring head is equipped with a vertical sliding stroke of 50 mm / 2” including automatic contact with test surface.

The stroke also allows easy and fast tests on pieces with different thicknesses without acting on the tester head or the elevating screw.

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.

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

Chances are you will never meet a similar test condition (as shown left) with a foam support under your test piece. At Affri we test each instrument under extreme conditions to assure the accuracy of every test.

The top surface referencing design minimizes errors caused by anvil ling problems associated with dirt or scale. This reduces sample preparation time and increases both accuracy and speed.

Absolute accuracy is assured even at the first indentation test. The constant clamping surface assures the right measurement with no need to repeat the test. The first result is correct and ABSOLUTE!
