HMV-G Series Micro Vickers Hardness Testers
This micro hardness tester features a built-in CCD camera for standardized automatic length measurement. Hardness can be measured simply and accurately with easy-touse PC software. The lineup also includes fully automated (FA) machines equipped with an electrically driven revolver mechanism and electrically driven XYZ. A manual machine with an optical head and models with color cameras are also included in the lineup.
In Vickers hardness measurements, the diagonal length of the indentation must be measured. With the PC software for the HMV-G series, images are acquired by the digital camera, and the diagonal length of the indentation is measured automatically. This eliminates human error and leads to stable results.
The main sequence of operations is laid out in a way that is easy to visualize, so the system can be used easily by anyone.

Word Report Function
A test results report is created automatically in Word format. Creating a template (.dotx format) in advance enables reports to be created automatically in an original layout.
* Microsoft Word 2016 or later is required to change the la yout.
* Direct conversion to PDF files is possible even if Word ha s not been installed on the PC.
Improving the Reliability of Test Results Data
Managing the Data from a Server PC is Preferred
- The results are saved automatically
- They can also be saved to a PC on the network.
Managing who Did the Testing is Preferred
Were the results from manual measurements altered arbitrarily?
- Saving the name of the experimenter
- Password restrictions on manual measurements
Image Quality Adjustment Function for Each Lens
If the camera image brightness and other visual qualities are changed for each lens, the image quality adjustments (such as brightness and contrast) can be saved separately.
Routine Inspection Graphs
Data graphs can be created just by selecting the daily results.
Edge Detection and Automatic Edge Pattern Creating Function
The software automatically detects the sample edges, and then automatically creates a parallel pattern, region pattern, or perpendicular/zigzag pattern.
For circular samples, a circular pattern can be created in which the central coordinates are automatically calculated, and the user congures the angle/radius for the test position.
Automatic Test Pattern Creating Function
The test position pattern is set automatically. There are 10 configurable patterns (a user-designated position can also be set).
Testing Automobile Gears
The system can detect the gear edges, and measure the hardness within the gear. Additionally, the test force can be changed for each test position.
Measuring the Depth of Hardening
(JIS G 0559 and ISO 3754)
The depth of hardening can be determined to check the amount of quenching.
Electric Micrometer (Optionally Available)
The electric XY stage function can be used by replacing the micrometer head on the HMV-G31 manual stage. It can be installed in existing HMV-G21/HMV-G31 systems.
* XY directions only. There is no electric micrometer for the Z axis direction.

High Resolution Color Camera Type
If visual inspection of the surface color is required in order to check the condition of the sample surface before testing, the sample can be positioned in the hardness tester, the sample surface can be checked, and then the sample can be tested as is.
