900-356 Large Frame Digital
Motorized BRINELL Hardness Tester
- • 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: 3.18-650HBW
- • 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
- • 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.
