Specification:

• 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 from optical microscope by operator then calculating the test value.
• The HBA-3000A tester can connect any PC with USB port and runing the SPC software, then the special software supplying simplest operation as following.

• Both single testing and batch testing mode are available
• Tolerance setting, distinguishing and alarming
• Statistics values such as Max, Min, Avg, R and S are available
• Convert test result to other scales, such as HRC, HRB, HRA, HV, σb
• All test results and indention images are saved automatically
• Test report created in Microsoft EXCEL format, can be edit, copy, print as you will
• Software update freely
