Brinell Hardness Tester
The Starrett 3825 Brinell Hardness Tester incorporates the latest load cell and closed loop 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 Brinell hardness measurements at all test loads up to 0.5%. Load overshoot and undershoot, which are common in traditional dead weight or open-loop systems, are 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 Brinell Hardness Tester is 50% less than the traditional dead weight type tester. Test load selection by keyboard and LCD screen.
The Brinell hardness tester features a fully automatic test cycle, load application, holding, and unloading are performed fully automatically. This greatly improves the reproducibility of test results since operator influence is eliminated. The directions for 0.102F/D2 ratios selected according to the materials and hardness range can be seen on the screen. Equipped with a 20X optical microscope to measure the diameter of the Brinell indention. The Brinell Hardness Calculator (BHC) makes the Brinell hardness value calculation easier and more convenient.
