Automatic Brinell Hardness Tester With Software BH-3000T
The Brinell hardness testing creates the largest indentation
comparing all other hardness testing methods. It is able to reflect
the comprehensive features of the material, and is unaffected by
the microstructure and inhomogeneous of the specimen. So it with
high precision and widely used in industry such as metallurgy,
forging, casting, unhardened steel and nonferrous metals, as well
as in the laboratories, universities , and scientific research
institutes.
BH-3000T Tester conforms to:
ISO6506 Metallic Materials-Brinell Hardness Test
ASTM E-10 Test Method for Brinell Hardness of Metallic Materials
Specification:
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.
Equipped with the special Brinell indention measure system which
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 by operator then calculating the test value.
The BH-3000T tester can connect any PC with USB port and runing the
SPC software, then the special software supplying simplest
operation as following.
Both single testing and batch testing mode are available
Tolerance setting, distinguishing and alarming
Statistics values such as Max, Min, Avg, R and S are available
Convert test result to other scales, such as HRC,HRB,HRA,HV,ｍb
All test results and indention images are saved automatically
Test report created in Microsoft EXCEL format, can be edit, copy,
print as you will
Software update freely
