  • 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 the special Brinell indention measure system which can measure the Brinell indention accurately, quickly, reliably. It is a new measuring method by using CCD camera to capture the indention image, instead of reading diameter．
