Attention
The hardness is one of the important parameters to determine the
mechanical properties of the material, and the hardness test is a
way which is used to discriminate and determine the quality of
metallic materials or components of the product. The so-called
hardness is meant the capability of the material which, under a
certain condition, is capable to resist the press-in of another matter
which will not produce residual deformation itself. The larger the
resisting power is, the higher the hardness will be, and vice versa.
In the course of testing the mechanical properties, hardness
measurement is the easiest, most economical, and rapidest method,
and is also one of the measures which are used to inspect the
quality of the product during manufacturing the machine. As the
metallic hardness possesses the mutual corresponding relationship
with certain other mechanic properties, hence, most metallic
materials may approximately infer their other mechanical properties
such as strength, fatigue, creep, wearing and internal damages etc.
by determining their hardness.
Following the daily growing development of the industrial and
agricultural production as well as the scientific technology, various
kinds of different requirements are also demanded to the hardness
tester itself, especially it demands high precision in measurement
and test, and may carry out various kinds of hardness test for
different kinds of materials. Based upon this, the model ISH-BRV
Brinell, Rockwell and Vickers hardness tester which is produced by
our factory possesses the conditions which fulfill all the above
mentioned requirements.

General descriptions:
Main application and characteristics:
This hardness tester possesses multistage test forces and many
kinds of indenters (table 1) which are used to measure and
determine the Brinell, Rockwell and Vickers hardness of the metallic
materials or test pieces. It is adaptable for determining the
hardness of ferrous metals (steel, cast iron pieces, mild steel and
quenched steel etc.) and non-ferrous metal (aluminium alloy and
