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 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.
