Touch Screen Brinel Rockwell Vickers Universal Brinell Testing
Machine Brinell Hardness Machine HBRV-187.5DX
Introduction:
Digital multi-functional universal hardness tester has Brinell,
Rockwell, Vickers three testing methods, has seven grade test force
,it can meet the needs of a variety of hardness tests. Test force
loading, dwell, unload adopted automatic switching mechanism, test
force transformation obtained by the rotation of hand wheel,
indentation measured by precision encoder and sensor and calculated
the hardness value by the internal system program. Easy to operate,
fast and intuitive interface, basically, no human operation error,
with its high sensitivity, stability, it is suitable for workshops
and laboratories.
The main function:
- Including Brinell, Rockwell, Vickers three testing methods；
- Can convert to different hardness scales
- With selection funciton of dwell time
- Time and date can be modified by user
- Can be output of testing results
The main features:
1. Electronic and electric loading, high precision sensor, with a
unique closed-loop control system
2. Eyepiece structure with digital encoder, measuring D1, D2 value,
LCD directly display hardness value and D1, D2 value
3. Directly select the hardness scale, the force value
automatically changes in the test parameters
4.The test force can be automatically corrected, and each force is
automatically compensated. The accuracy of the force is improved by
an order of magnitude
5. The tester can be calibrated according to standard hardness
block or length scale
6.The test force can be automatically corrected by standard
dynamometer
7. The hardness values can be converted among brinell, rockwell and
vickers
8. Touch screen display, easy to operate
9.Automatic hardness conversion according to national standard and
ASTM standard
10.Can set password protection setting parameters, more sample and
test information
11. Memory disk of measurement data is saved in EXCEL format for
easy editing and processing
