Brinell hardness tester Integral1  

Integral 1

Automatic digital hardness tester for Brinell test method in compliance with ASTM E10 and ISO 6506 hardness standards. Integral 1 is a top level bench hardness tester for fully automatic Brinell test cycles. It is entirely motorized with an automatic turret with indenter and magnification lenses for Brinell indent autoreading after indentation. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). Exact hardness result on the first test and R&R data at the top of his 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. Hardness testing on every metals: iron, steel, tempered steel, cast iron, brass, aluminium, copper and metal alloys.

Test loads: from 15,6 to 3000 kgf (From 153,2 to 29421 N)

Brinell ISO 6506 / ASTM E-10: HBW1/30 - HBW2.5/15.625 - HBW2.5/31.25 - HBW2.5/62.5 - HBW2.5/187.5 - HBW5/25 - HRW5/62,5 - HBW5/125 - HBW5/250 - HBW5/750 - HBW10/100 - HBW10/250 - HBW10/500 - HBW10/1000 - HBW10/1500 - HBW10/3000


One input for the entire test cycle

Brinell hardness tester Integral StartThe hardness tester’s head moves down until contact is made, clamps the piece, applies the force and makes the indentation. The software will move to the camera view mode where the indentation is automatically measured.

Closed Loop (Pat. AFFRI)

Hardness tester Closed LoopClosed loop load cells control load forces with a frequency of 1 khz, assuring perfect linearity in every range. Results are not affected by any structural deflection, misalignment or vibration.

Repeatability and reproducibility (R%R)

Brinell hardness tester Integral repeatabilityAccurate measurements on the first test, even in extreme conditions, eliminates the need for repeated tests. The R&R data is at the top of its class.

Clamping system (Pat. AFFRI)

Brinell hardness tester ClampingSecure contact with the specimen is always maintained, even in the unlikely event of any specimen movement during the operation cycle. The clamping system assures complete stability of any test piece throughout the test cycle, even if it's oiled, rusty or dirty.

Motorized head

Brinell hardness tester Integral Motorized headAutomatic movements with automatic stop when contact is made. Total of 500 mm of motorized vertical stroke. The approach of the head moving to the piece as opposed to the piece moving to the head allows for more accurate, stable and safe measurements.

Motorized X/Y table

Brinell hardness tester Integral Motorized tableFor automatic multi-indentation measurement. The user can program and set the number of indentations to be performed and the related movement of the X/Y table before each indent.

Motorized turret

Brinell hardness tester Integral Motorized turretMultiples slots for different ball indenters, magnification lenses and even a milling surface preparation tool. Auto-rotating and tool switching for a completely automatic single or multi indentation measurement cycle.


Brinell hardness tester Integral autofocusThe Auto Focus performs an automatic focus adjustment for the selected optic with precise positioning at any magnification. This system reduces reading time while also assuring high reading accuracy.

Large base

Brinell Hardness tester Integral baseThe wide work table base is capable of bearing masses beyond 3000 kg and special fixtures or anviling. Hardness measurements on bulky and irregular test pieces which cannot be easily reached by the regular bench hardness testers.

Remote support

Brinell hardness tester Integral remote supportIntegral 1 can be remotely connected to AFFRI Engineers from anywhere in the world. Our experts can diagnose any technical issues, provide additional operator training and update the software.


The software controls the whole instrument avoiding setting errors or operators mistakes:
Brinell hardness tester Integral softwareSetup the hardness test scales, the load time, the properties of the camera, the test method standards and the conversion scales.
Brinell hardness tester Integral software1Manage the instrument tools and check if the installed tool is correct for the selected hardness test method.
Brinell hardness tester Integral software2Lists all of the readings done and their associated image. Chart the results and statistics highlighted according to their tolerance values (LOW, OK, HIGH).
