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.
◆ 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 a 20X optical microscope to measure the diameter of Brinell indentation. It is an economic scheme for Brinell testing.
◆ Brinell Hardness Caculator (BHC) make the hardness value calculation more easier and convenient. Hardness value will showing on screen directly when the indentation diameter inputted.
