Portable Hardness Tester

900-356 Large Frame Digital
Motorized BRINELL Hardness Tester

Specifications:

• 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 Brinell hardness 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 gross weight of the tester is 50% less than the traditional dead weights type testers.
• Test load selection by keypad and shown on the LCD screen.
• Fully automatic test cycles. The Brinell hardness Tester features a fully automatic test cycle, load application, dwell, unloading, is performed fully automatically. This greatly improves reproducibility of test results since operator influence is eliminated.
• Selectable dwell times by screen. The indenter, load, and other test information are shown 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 indention.
• Brinell Hardness Calculator (BHC) makes the hardness value calculation easy and convenient.
