Main Function：

DVKS-1XYZ automatic digital Micro Vickers and Knoop hardness tester is a high-tech and new product combining the optics, mechanic and electrics features. With a novel and pleasing appearance, the internal structure is mainly made by stainless steel parts, has better performance. It adopts a new type of automatic turret mechanism, equipped with both Micro Vickers and Knoop indenters. These two indenters adopt the independent alignment device which ensures that Vickers and Knoop indentation are at the same center position. It can directly shows the test mode, test force, indentation length, dwell time, test numbers, conversion scale, date and time on the large screen. As long as press the eyepiece button after measuring the indentation length, it can automatically get the hardness value and shows on the screen. With the up and down limit alarm function, test results can be saved for checking or be printed out by the built-in printer, and with RS232 interface for connecting to the computer. It can use optional Knoop indenter to measure Knoop hardness. And it can be equipped with LCD video measuring device and CCD image automatic measuring system.

Application range:

Suitable for ferrous metal, non-ferrous metals, IC thin sections, coatings, ply-metals; glass, ceramics, agate, precious stones, thin plastic sections etc.; hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers.

Technical Specification：

Software Function:

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.

Measuring linkage: The software controls the turret, loading and directly reading the Vickers hardness value.

Image acquisition: Real time display of hardness image, store and print image.

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 once loading.

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. of hardness.

Linkage control: Through the communication interface the system percepts the test force changes, controls the turret and directly reads.

Automatic displacement: Equipped with high precision X-Y automatic test table.

Automatic identification: Leading indentation automatic identification technology, read D1 / D2 and HV value in 0.3 seconds.

Stable performance: The indentation of non mirror polishing, uneven light, not in the center can be read automatically.

Powerful functions: Such as manual reading, automatic reading, hardness conversion, depth-hardness curve, indentation image, picture and text report.

Easy to use: Through the hardness block calibration, in line with the users’ habits. It can be normal used with half day training.

Automatic reading: Original algorithm of automatic reading to automatic read a variety of indentation with fast speed and high accuracy.

Good repeatability: It is automatic reading with high repeatability and can satisfy the requirement of professional users.

Automatic scanning: Can automatically scan the sample edge and shape.

Z axis move and autofocus: click the Auto Focus button and the system will start auto-focusing.
