Rockwell
Rockwell hardness testing is a general method for
measuring the hardness of metallic and polymer
materials. Rockwell hardness testing is an indentation
testing method. The indenter is either a conical diamond
(brale) or a hard steel ball. Different indenter ball
diameters from 1/16 to 1/2 inch are used depending on
the test scale.
Macro-Vickers
Macro Vickers is mostly used for small parts, finished
components and case depth work. The Vickers method is
based on an optical measurement system. A square base
pyramid shaped diamond is used for testing in the
Vickers scale. Typically loads are very light, ranging from
5kg to 50kg.
Micro-Vickers
Micro Vickers is mostly used for small parts, thin sections,
or case depth work. The Vickers method is based on an
optical measurement system. A square base pyramid
shaped diamond is used for testing in the Vickers scale.
Typically loads are very light, ranging 10 grams to 1000
grams.
Hardness Testers
We offer a wide range of hardness testers for a variety of
applications. These machines can be supplied new or
reconditioned.
We cover the complete range including Rockwell, Brinell,
Vickers and Micro-Vickers and Portable Hardness Testers.
All machines come complete with a warranty and
calibration is available on-site
Brinell
The Brinell hardness test method as used to determine
Brinell hardness, is defined in ASTM E10. Most commonly
it is used to test materials that have a structure that is
too coarse or that have a surface that is too rough to be
tested using another test method, e.g., castings and
forgings. Brinell testing often use a very high test load
(3000kgf) and a 10mm wide indenter so that the
resulting indentation averages out most surface and sub-
surface inconsistencies.
Hardness Tester Product Range
We supply all major types of hardness testers -
Rockwell, Vickers, Brinell and Universal which combine
all the previous three types of hardness testers,
together with portable devices so that testing can be
performed more conveniently.
Our commitment to you does not end once you have
bought a hardness tester from us. We can offer on-
site service and calibration contracts to ensure your
machine is maintained in first class condition. Please
contact us for further details..

Universal Testers
As the name suggests, it is a machine that offers the
measurement of Rockwell Vickers and Brinell Scales.
Due to its versatility it is equipped with different types
of indenter and measuring methods of the indents
created.
Portable Testers
The Leeb rebound hardness test method was
developed in 1975 by Leeb and Brandestini at Proceq
SA to provide a portable hardness test for metals. It
was developed as an alternative to the unwieldy and
sometimes intricate traditional hardness measuring
equipment.
Traditional hardness measurements, e.g., those of
Rockwell, Vickers, and Brinell are stationary, requiring
fixed workstations in segregated testing areas or
laboratories. The portability of Leeb testers can
sometimes help to achieve higher testing rates without
destruction of samples, which in turn simplifies
processes and reduces cost.
