One Drive Measurements

Rockwell hardness testers RSD are extremely accurate system with automatic preloading, loading and measurements. RSD 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 appears on the display.

Only 3″ for one hardness test! (more with standardized dwell time)

• Auto-contact with the specimen
• Automatic clamping and activation of the reference surface point
• Auto preloading and loading
• Automatic measure
• Auto-return stroke when releasing the lever

Auto-Contact And Test Activation

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.

Clamping To The Limit

Secure contact with the specimen is always maintained, even in the unlikely event of any specimen movement during the operation cycle. The clamping system blocks the specimen before the measurement cycle, it moves with the head for the whole measuring stroke generating a constant pressure. The clamping system assures perfect stability of any test piece throughout the test cycle.

The clamping works automatically when pulling the lever! It can’t be easier than this!

• Perfect stability of any test piece throughout the test cycle
• Safe testing on oiled, rusty or dirty samples
• No more need for pedestals or additional support for the specimen
• The indenter is protected and retracted minimizing the risk of accidental damages.
• Test long bars, tubes or rings in just few seconds

Incredible AFFRI Performance

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!

Infinite Capacity

700 mm of vertical stroke or more. The moving tester’s head permits easy measurements on large pieces, reaching points at the top of the sample that would be difficult to be measured with common testers.

Open Space

The wide working base is capable of bearing masses beyond 2000 kg which allows for steady hardness measurements on bulky or irregular pieces. It also offers a comfortable working base for small pieces.

Custom Bases

Optional interchangeable base for hardness testing on external ring shape tubes, cylindrical surfaces and various samples diameter. Made by AFFRI, the tester stand can be designed for every special needs.
