KASON US-187.5W Computerised Digital Universal Hardness Tester
1 9 YEARS
Development Base of Advanced Testing machine Of China
Features:
*KASON US-187.5W Universal/ Brinell Rockwell & Vickers hardness tester is used electronic loading controlinstead of weight loading control,it is equipped with a newly-designed large displaying screen with goodreliability, excellent operation and easy watching, thus it is a high-tech product combining the optic,mechanic and electric features.
*It has Brinell, Rockwell and Vickers three test modes and many levels of test force, which cantest several kinds of hardness.
*Test force loading, dwell, unload adopts automatic shifting for easy and fast operation.
*It can show and set the present scale, test force, test indenter, dwell time and hardnessconversion;
*The main function is as follows: Selection of Brinell, Rockwell and Vickers three test modes;Conversion scales of different kinds of hardness; Test results can be saved for checking or be printedout, automatic calculation of maximum, minimum and average value; can connect to the computer.
Applications:
Suitable for hardened and surface hardened steel, hard alloy steel, casting parts, non-ferrous metals,various kinds of hardening and tempering steel and tempered steel, carburized steel sheet, softmetals, surface heat treating and chemical treating materials etc.

Description of Measuring System:
Vickers:
* The CCD image processing system can finish the process automatically: measurement of the diagonallength 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 inspectedwhether 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 * Inquire the saved data and image at any time
* Customer may adjust the accuracy of the measured hardness value at any time according to thecalibration of Hardness Tester
* The measured HV value can be converted to other hardness scales(HB,HRetc)
* System provides a rich set of image procsessing tools for advanced users.the standard tools in thesystem 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 infiltering and finding edges,as well as some standard tools in morphological operations such asOpen,Close,Dilation,Erosion,Skeletonize,and Flood Fill etc
