Electric Brinell, Rockwell, Vickers Hardness Tester (HBRV-187.5)
HBRV-187.5 Blowi hardness tester is a multi-purpose multi-purpose
hardness tester with three test methods of Brinell, Rockwell and
Vickers and seven-level test force, which can meet the requirements
of users for various hardness tests. After the initial test force
is manually loaded, the loading, holding and unloading of the total
test force are automatically completed. It has a wide range of use
and convenient operation. It is a hardness tester commonly used by
industrial and mining enterprises and scientific research
institutions.
Main features of the instrument
1. The optical system designed by senior optical engineers not only
has clear images, but also can be used as a simple microscope, with
adjustable brightness, comfortable vision, and not easy to fatigue
after long-term operation;
2. It has three test methods, Brinell, Rockwell and Vickers, and
seven-level test force, which can meet various hardness test
requirements;
3. The cast shell has a stable and non-deformed structure in
one-time molding, high-grade pure white car paint, strong scratch
resistance, and it is still bright as new after many years of use;
4. Our company has the ability to research, develop, design,
produce and process by ourselves, and provide parts replacement and
maintenance upgrade services for our machines for life;
The main purpose and scope of use of the instrument:
1. Determine the Brinell, Vickers and Rockwell hardness of ferrous
metals, non-ferrous metals and cemented carbides:
2. Brinell hardness of castings, annealed steel, normalized steel,
non-ferrous metals and soft alloys;
3. Rockwell hardness of heat-treated materials such as quenching
and quenching and tempering;
4. Vickers hardness of nitriding layer, ceramics, thin plates,
metal flakes, electroplating layers, and small parts;
