Innovative closed-loop technology. The tester incorporates the latest load cell technology. The test load is applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit. The result is highly
accurate measurements at all test loads up to 0.5%. The common load overshoot or undershoot as known
from traditional dead weight, or open-loop, systems is eliminated. The absence of mechanical weights not only eliminates friction problems
but also makes the equipment less sensitive to misalignments caused by vibrations.
The whole weight of the tester is 50% less than the traditional dead weights type tester.
Test load selection by keyboard and LCD screen. No need of handling heavy weights or cleaning the messy oil.
Fully automatic test cycles. The hardness Tester features a fully automatic test cycle, load application, holding,
unloading, is performed fully automaticly. This greatly improves reproducibility of test results since operator
influence is eliminated.
Selectable dwell times by screen. The indenter, load, and other test informations are showing clearly on the
large LCD screen.
The directions for 0.102F/D2 ratios selecting according to the materials and hardness range can be showing
on the screen.
Separated CCD Camera make the test more flexible and movable.
The special Brinell indention measure system can measure the Brinell indention accurately, quickly, reliably.
It is a new measuring method by using CCD camera to capture the indention image, instead of reading
diameter from optical microscope.

Usage Range
Brinell hardness test that shows largest indentation among all hardness tests is able to reflect the comprehensive features of material, and the test is unaffected by the organization micro-segregation and the componential unevenness of specimen; and hence it is a hardness testing method with high precision. The Brinell hardness test is widely used in such industrial fields as metallurgy, forging, casting, unhardened steel and non-ferrous metals industries, as well as in laboratories, universities, colleges and scientific research institutes.
