Functional features:

MHV-5Z/10Z/30Z/50Z/V2.0The automatic Vickers hardness tester integrates various latest professional technologies such as optical imaging, mechanical displacement, electronic control, digital imaging, image analysis, and computer processing. The control of the Vickers hardness tester and automatic stage is achieved through a computer host, and the hardness indentation is digitized and imaged on the computer screen. Then, through automatic reading, manual reading and other means, the microhardness, hardening layer depth, film thickness, two-point spacing, etc. of metal and some non-metallic materials, as well as various film layers and coatings, are accurately measured. It can also capture the surface morphology of metals and perform fixed magnification printing. This system breaks through the traditional hardness testing method and achieves semi-automatic, high-precision, and high repeatability hardness testing, making it an important equipment for material analysis.

Main parameters:

Software functions:

System linkage: Through serial communication of the hardness tester, the system is linked with the hardness tester.

Pressure linkage: When the hardness tester test force is converted, the system senses the change in test force and displays it in real-time in the system.

Rotary tower linkage: software controlled hardness tester for objective lens—The indenter switches between each other without the need for manual control of the hardness tester.

Loading linkage: The software controls the hardness tester to load, without the need for manual control of the hardness tester.

Measurement linkage: Software controls the turret of the hardness tester, loads and directly reads the Vickers hardness value.

Optical linkage: manual focusing.

Image acquisition: Real time display of hardness images, capable of storing and printing images.

Automatic measurement: Automatically identify the four vertices of the indentation, fast speed, accurate data, and multiple professional algorithms to apply to different indentations. Continuous testing, instant testing, and specified coordinate compression.

Automatic point finding: Take points near the four vertices of the indentation, and the system automatically finds the best vertex, greatly reducing human error.

Diagonal measurement: Point at the upper left and lower right corners of the indentation to read the hardness value.

Four point measurement: Take the four vertices of the indentation and read the hardness value.

Hardness conversion: According to national standards, automatically perform Brinell hardness conversion—rockwell—Vickers—Convert various hardness values such as Nusselt hardness and display them in real-time.

Graphic report: Automatically record measurement data and generate hardness automatically—Depth curve, save or print hardness—Depth curve and all indentation measurements. Save or print the indentation image and the current indentation hardness value. All reports according toWORDDocument saving.

Result statistics: Measure the results of multiple indentations usingEXCELExport data format and automatically calculate measurement times, maximum and minimum hardness values, average values, variance, etc.

Linkage control: The system senses changes in test force, controls the hardness tester turret, loads and directly reads through serial communication.

Automatic displacement: configured with high precisionX-YAutomated platform.

Automatic recognition: Leading indentation automatic recognition technology, in 0.3 Read within secondsD1/D2andHVValue.

Stable performance: It can automatically read non mirror polishing, uneven lighting, and non center indentation.

Powerful features: manual reading, automatic reading, hardness conversion, depth hardness curve, indentation image, graphic and textual report functions.

Easy to use: calibrated through hardness blocks, in line with users' daily habits. After half a day of training, it can be used normally.

Automatic reading: With a unique automatic reading algorithm, it can automatically read multiple types of indentations with fast speed and high accuracy.

Good repeatability: The automatic reading has high repeatability, meeting the professional requirements of users.

Automatic scanning: capable of automatically scanning the edges and contours of the sample.
