Fully Automatic Hardness Tester 0.0625μm Resolution with Automatic
MHV-5Z/10Z/30Z/50Z /V3.0 Fully Automatic Vickers Hardness Tester
MHV-5Z/10Z/30Z/50Z/V3.0 Fully Automatic Vickers Hardness Tester is
integrated with several new technologies such as optical imaging,
mechanical displacement, electronic control, digital imaging, image
analysis, computer processing and so on. It controls the Vickers
hardness tester and automatic test table by the computer, and
displays the indentation image on the computer screen. By means of
automatic reading and manual reading, it accurately measures the HV
hardness, hardening depth, film thickness, distance between two
points of metals and some non-metallic materials and various films.
It also can shoot metal surface morphology and taking fixed rate
printing etc. This system breaks through the traditional test
method, realize the hardness test of fully automatic, high
precision, high repeatability, and it is the important equipment
for materials analysis.

System linkage: Through the communication interface it realizes the
linkage between the system and the hardness tester.
Pressure linkage: When converting test force, the system percepts
the test force change and displays in real time.
Turret linkage: The software controls the shifting between the
objective and the indenter without manual control.
Loading linkage: The software controls the loading without manual
Measuring linkage: The software controls the turret, loading and
directly reading the Vickers hardness value.
Light source linkage: Automatic focus.
Image acquisition: Real time display of hardness image, store and
Automatic measurement: Automatically find the four vertices of
indentation with fast speed and accurate data, there are many
professional algorithms to be suitable for different indentation.
It continuously and immediately measures at specified coordinates
Automatic point search: The system automatically finds the best
vertices near the four vertices of the indentation, greatly reduce
the human error.
Diagonal measurement: Click the top left and lower right corner of
the indentation, you can read the hardness value.
Four point measurement: Click the four point of the indentation and
you can read the hardness value.
Hardness conversion: According to the national standard,
automatically convert the hardness value between Brinell, Rockwell,
Vickers, Knoop, real-time display.
Graphic report: Automatic record of measurement data, automatic
generation of hardness-depth curves, saving or printing the
hardness-depth curves and all indentation measurements. Save or
print the indentation image and the current indentation hardness
value. All the reports are saved in WORD file.
Results statistics: Output the multiple measured results of
indentations by EXCEL and automatically count the measurement
number, maximum value, minimum value, average value, variance, etc.
