Affri Automatic Universal Hardness Tester – LD3000AX

Rockwell, Superficial Rockwell, Brinell, Brinell HBT, and Vickers. Automatic hardness testing machine with test loads from 1 to 3000 kgf. Hardness measurements on every metal and alloys conforming to ASTM, DIN EN ISO international standards.

Fully motorized and automatic, the test is not affected by operator influences and can easily be used by operators of every level



LD3000AX is an automatic system for Brinell, Vickers, Rockwell and Superficial Rockwell hardness test methods in compliance with ASTM and ISO hardness standards. 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.

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

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



  • The activation of the test cycle is automatic, it starts when the head makes contact with the specimen which is automatically recognized at any position within the vertical stroke.
  • The top surface referencing design minimizes errors caused by problems associated with dirt or scale.
  • This reduces sample preparation time and increases both accuracy and speed.

Vertical capacity from indenter to the base 300mm / 12″ (more on request)

Horizontal capacity from column to the indenter 190 mm / 7.4” (more on request)

The LD3000AX hardness tester is a robust, reliable system, designed to function even in hostile environments. Heavy and bulky samples can be easily placed using a forklift or overhead-traveling crane.



When testing unstable samples or deflecting parts, the AFFRI System will follow the sample without losing contact thanks to its 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.
