Affri Automatic Universal Hardness Tester – Integral Revolver Series

Universal hardness tester for automatic Brinell, Vickers, Rockwell, Superficial Rockwell, Shore and CHD test methods in compliance with ASTM and ISO hardness standards. Integral is a top-level bench hardness tester for fully automatic test cycles. It is entirely motorized and equipped with an automatic turret with indenters and magnification lenses for indent auto-reading after indentation. This multifunctional turret allows multiple tests in different hardness scales with just one tester, without the need to change indenters or lenses when changing hardness method. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). The exact hardness result on the first test and R&R data are at the top of its class, absolute accuracy (better than 0.5 %) in every condition. Integral 1 has a large, fixed base and a motorized head with long vertical stroke. Wide touchscreen and a user-friendly interface for ease in test planning and a clear view of results. Statistics and diagrams are automatically generated and can be stored with test sessions in the large archive. Hardness tests on all metals: iron, steel, tempered steel, cast iron, brass, aluminium, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hard facing. Hard and soft plastics.



Universal hardness tester Integral Revolver is a fully motorized system for automatic loading and optical measurement through camera. AFFRI System hardness testers achieve the highest level of load accuracy and measurement resolution available for hardness tests. Thanks to the AFFRI System, the real indentation measurement is guaranteed without any external interference in any condition.


How to do a hardness measurement?

The hardness measurements are very easy, quick and absolute. The hardness test cycle is fully automatic and motorized in just one drive (button or icon):

  1. Automatic contact with the specimen
  2. Auto-active sliding clamping
  3. Automatic preloading and loading
  4. Auto-switching to optic lens
  5. Autofocus by image scanning brightness
  6. Auto measure and result display
  7. Automatic return stroke at programmed distance



When testing unstable samples or deflecting parts, the AFFRI System will follow the sample without losing contact thanks to its infinite stroke for indenter and clamping hood.



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.
