[Brinell Hardness Tester　KB3000E Product details]:
Product Specification:

•  KB-3000E is equipped with a 20X optical microscope, economic type.
•  It conforms to  ISO6506, ASTM E-10.


•  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.
•  It with high precision and widely used in industry such as metallurgy, forging, casting, unhardened steel and nonferrous metals.
•  It is used  in the laboratories, universities , and scientific research institutes.

•  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.
•  The tester 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.
•  20X Microscope with LED lighting source make the indention more distinguishable and improving the measure accurate.
