HVW-30Z Computerised Automatic Turret Vickers Hardness Tester
The computer is installed with a professional Vickers hardness measurement system to improve the accuracy and repeatability of the measurement. The Vickers hardness tester image analysis system connects the hardness tester to the computer through the CCD camera interface, the whole testing process can be completed through simple operation of the keyboard and mouse, easy to operate, high measurement accuracy, minimising human error and avoiding visual fatigue of the operator.
Product features：
The body of the product is formed in one piece by the casting process and is subjected to a long aging process. Compared to the piecing process, the long-term use of deformation is extremely small, and can effectively adapt to a variety of harsh environments.
Automotive baking paint, high grade lacquer, scratch resistance, still shiny as new after years of use.
an optical system designed by a senior optical engineer not only for clear images but also for use as a simple microscope with adjustable brightness, comfortable vision and non-fatiguing operation over long periods of time equipped with an automatic turret, the operator can easily and freely switch between high and low magnification objectives to observe and measure the specimen, avoiding damage to the optical objective, indenter and test force system from human handling habits.
Optional CCD image processing system and video measuring device.
Equipped with Bluetooth module, Bluetooth printer and optional Bluetooth PC receiver for wireless printing and wireless data transmission
Accuracy in accordance with GB/T4340.2 ISO6507-2 and ASTM E384.
The software image interface is large (800*600) and the image is clearer, which effectively reduces operational errors.
High resolution industrial camera for microscopic imaging and macro imaging. Its compact size, clear image and good imaging quality.
Convenient and practical conversion function for various hardness scales; in addition, the software has a built-in hardness and strength conversion table, which will never be lost
Powerful data reporting functions.
Test data, indentation pictures and hardness gradient graphs can be exported simultaneously for more convincing results.
When doing hardness gradient tests, the hardness gradient graph can be drawn automatically.
The header of the report, e.g. company name, title, etc. can be set and saved in advance for easy printing of the report.
The image frame can be opened partially and then enlarged, so that the measurement points can be taken more accurately and errors can be reduced.
Hardness correction function, if a point is found to be not taken correctly when measuring, it can be adjusted and corrected instantly.
The indentation image can be adjusted for contrast, brightness, etc.
Hardness calibration function: direct input of the hardness value for comparison, convenient and fast.
The image file and data file can be opened, stored and printed separately.
Ability to view data files and image files at any time; data files are typed in the form of tables, images and curves
Leading-edge indentation automatic recognition technology, reads out D1/D2 and HV values within 0.3 seconds
Automatic reading of non-mirror polished, unevenly lit, out-of-centre indentations
Automatic reading, manual reading, hardness conversion, depth hardness curve, indentation image and graphic report functions.
Original automatic reading algorithm, automatic reading of a wide range of indentations with high speed and accuracy.
High repeatability of automatic readings to meet professional user requirements.
