HVT-50/HVT-50A Vickers Hardness Tester with Measuring System
* high-tech and new product combining the optics, mechanic and electrics features;
* adopts load cell control system, improves the precision of the test force and the repeatability and stability of the indicating value;
* shows the test force, dwell time, test numbers on the screen, only need to input the diagonal of the indentation when operation, it can automatically get the hardness value and shows on the screen.
* It can be equipped with CCD image automatic measuring system;
*The instrument adopts closed-loop loading control system;
* Precision conforms to GB/T 4340.2, ISO 6507-2 and ASTM E92

* The CCD image processing system can finish the process automatically: measurement of the diagonal length of indentation, hardness value display, testing data and image saving, etc.
* It is available to preset the upper and lower limit of hardness value, the testing result can be inspected whether it is qualified automatically.
* Proceed hardness testing on 20 test points at one time (preset the distance between test points at will), and save the testing results as one group.
* Converting between various hardness scales and tensile strength
* Inquire the saved data and image at any time
* Customer may adjust the accuracy of the measured hardness value at any time according to the calibration of Hardness Tester
* The measured HV value can be converted to the other hardness scales such as HB,HR etc.
* System provides a rich set of image processing tools for advanced users. the standard tools in the system include adjusting Brightness, Contrast, Gamma, and Histogram Level, and the Sharpen, Smooth, Invert, and Convert to Grey functions. On grey scale images, system provides various advanced tools in filtering and finding edges, as well as some standard tools in morphological operations such as Open, Close, Dilation, Erosion, Skeletonize, and Flood Fill, to name a few.
* System provides the tools to draw and measure common geometric shapes such as lines, angles 4-point angles (for missing or hidden vertexes),rectangles, circles, ellipses, and polygons. Note that the measurement assumes the system is calibrated.
* System allows user manage multiple images in an album which can be saved to and opened from an album file. The images can have the standard geometric shapes and the documents as entered by user as described above
On an image, system provides a document editor to enter/edit documents with contents either in simple plain test format or in advanced HTML format with objects including tabs, list, and images.
*System can print the image with user specified magnification if it is calibrated.
