HBRV-187.5DX Brinell Hardness Machine Brinell Hardness Test
Equipment Knoop Hardness Test
HBRV-187.5DX Senior Digital Brinell, Rockwell, Vickers Universal
hardness testers series ( with Touch Screen)
Brief Introduction
Hardness is one of the important mechanic characteristics of the
material while the hardness testing is an important method to judge
the quality of the metal material or its component parts. The
hardness of the metal is correspondent to its mechanic
characteristics, and so its mechanic characteristics such as the
strength, tiredness, wriggling and wearing out can be tested out
approximately through its hardness testing .
Digital multi-functional hardness tester with Brinell, Rockwell,
Vickers three testing methods, multi-functional hardness tester of
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. So it is 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 as follows:
- Brinell, Rockwell, Vickers three testing methods；
- Conversion of different hardness scales
- Selection of dwell time
- Modifications of time and date
- Output of testing results
Main features:
- Equipped Brinell, Rockwell, Vickers test methods
2. Electronic and electric loading, high precision sensor, with a
unique closed-loop control system
3. Eyepiece structure with digital encoder, measuring D1, D2 value,
LCD directly display hardness value and D1, D2 value
4. Directly select the hardness scale, the force value
automatically changes in the test parameters
- The test force is automatically corrected, and each force is
automatically compensated. The accuracy of the force is improved by
an order of magnitude
- Can be calibrated according to standard hardness block or length
scale
- The test force can be automatically corrected by standard
dynamometer
8. The hardness values of brinell, rockwell and vickers can be
converted
- Touch screen, easy to operate
- Automatic hardness conversion according to national standard /ASTM
- Set password protection setting parameters, more sample and test
information
- U-disk of measurement data is saved in EXCEL format for easy
editing and processing
