900-355 DIGITAL MOTORIZED
BRINELL HARDNESS TESTER


Features:
  • Load Cell driven system provides precise control of test force application
  • Direct digital reading
  • Engineered to obtain highly sensitive and accurate readings
  • Perfect for laboratories, workshops, tool rooms, inspection labs, etc.
  • Measuring Range: 8-650HBW

Specifications:


  • Innovative closed-loop technology. The Brinell hardness 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 whole weight of the tester is 50% less than the traditional dead weights type tester.
  • Test load selection by keyboard and LCD screen.
  • Fully automatic test cycles. The Brinell hardness Tester features a fully automatic test cycle, load application, holding, 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) make the hardness value calculation easier and convenient.
