The Brinell bench hardness tester is a digital touchscreen instrument designed to perform Brinell HBW hardness tests on metallic materials. It is suitable for laboratory checks, quality-control departments and industrial applications where the test requires high loads, controlled force application and indentation reading.
The Brinell method is based on applying a ball indenter to the sample with a defined force for a specified time. After the test, the indentation left on the material is measured to determine the HBW hardness value.
The SAB3000HB operates over a range of 8–650 HBW and performs Brinell tests with loads from 62.5 to 3000 kgf. This makes it suitable for inspections on metallic materials where the test requires high force.
Load application is motorized and managed by load cells. This provides better control of the force applied during the test and more stable operating conditions than manual load application.
The dwell time can be adjusted from 1 to 60 seconds, allowing the test to be adapted to the material and the control procedure. Dwell-time adjustment is important because material behaviour during indentation can affect indentation quality and result consistency.
The instrument uses ball indenters with different diameters and operates on several Brinell scales, including HBW2.5, HBW5 and HBW10 with different loads. The combination of ball diameter and load must be selected according to the material, sample thickness and required HBW scale.
The built-in 20x microscope allows the indentation to be read directly on the instrument. After load application, the operator measures the indentation diameter and the instrument calculates the Brinell hardness value.
When a dedicated indentation-reading solution is preferred, or when inspection is managed separately from the hardness tester, a bench Brinell indentation tester or portable Brinell indentation testers can also be considered. These solutions are useful when indentation measurement needs to be managed more practically, especially for repeated checks or samples analysed at a separate workstation.
The touchscreen display makes test management, parameter selection and result viewing more immediate. Measured values can be stored, helping to organise tests performed on batches, samples or different components.
The built-in printer allows test results to be printed directly, making it easier to document completed checks. This is useful when the HBW value needs to be quickly associated with the inspected sample or when a paper record of the verification is required.
Compared with a multiscale bench hardness tester, which performs Rockwell, Brinell and Vickers tests with one instrument, the SAB3000HB is specifically designed for the Brinell method. It is therefore suitable when HBW testing is the main control reference and higher Brinell loads are required.
Sample preparation is essential. The surface must be clean, stable and sufficiently regular to obtain a correct indentation. Sample thickness must also be suitable for the selected load, avoiding deformation on the opposite side of the part after testing.
The Brinell bench hardness tester is suitable for metallic materials, castings, steels, cast irons, non-ferrous alloys and components compatible with the HBW test. Ball diameter, load and dwell time must be selected consistently with the material and the adopted control procedure.

FAQ – Brinell bench hardness tester
What is a Brinell bench hardness tester?
It is a laboratory instrument used to measure Brinell HBW hardness through an indentation test with a ball indenter and a defined load.
How does the Brinell test work?
The Brinell test applies a ball to the sample with a preset force for a defined time. After the test, the indentation diameter is measured to determine the HBW hardness value.
Which hardness scale does this instrument use?
The hardness tester operates on the Brinell HBW scale, with a measuring range from 8 to 650 HBW.
Which test loads are available?
The instrument performs Brinell tests with loads from 62.5 to 3000 kgf, selected according to the HBW scale, indenter and material to be tested.
Which indenters are used?
The Brinell test uses ball indenters. The instrument is supplied with 2.5 mm, 5 mm and 10 mm balls, to be selected according to the test to be performed.
What is the built-in microscope used for?
The built-in microscope allows the Brinell indentation to be read directly on the instrument by measuring the diameter of the indentation left by the indenter.
How can the Brinell indentation be read more conveniently?
The indentation can be read with the built-in microscope. When a dedicated indentation-measuring solution is preferred, Brinell indentation testers can also be used.
When should this instrument be selected instead of a multiscale bench hardness tester?
The Brinell bench hardness tester is suitable when the HBW method is the main control reference. A multiscale bench hardness tester is more suitable when Rockwell and Vickers tests are also required with the same instrument.
What is the purpose of motorized load application?
Motorized load application makes the test phase more controlled, improving the stability of force application compared with manual operation.
Is the dwell time adjustable?
Yes. The dwell time can be adjusted from 1 to 60 seconds to adapt the test to the material and the control procedure.
Can the instrument store results?
Yes. Measured values can be stored, making it easier to manage checks on several samples or batches.
Can test results be printed?
Yes. The instrument has a built-in printer for directly printing test results.
Does the sample surface need to be prepared?
Yes. The surface must be clean, stable and sufficiently regular to obtain a correct, readable indentation.
Is sample thickness important?
Yes. The sample must have adequate thickness for the selected load and must not deform on the opposite side after the test.
What is included as standard?
The standard supply includes 2.5 mm, 5 mm and 10 mm ball indenters, support tables, a V-shaped anvil and HBW test blocks.
