Through its preload and software function, the system can automatically test at the specified surface position. Once the test is completed, the automatic image analysis system will automatically generate indentation readings. Therefore, the test running time is greatly shortened, and the manual operation time is eliminated, thus improving the efficiency and productivity.
The most important factor to obtain accurate test results is the accuracy and stability of loading when testing Knoop or microhardness. The traditional weight loading hardness tester is influenced by inertia and friction, which is prone to overload or underload fluctuation, and the loading changes greatly.
Wolpert Wilson 2 100 series hardness tester adopts the most advanced closed-loop force sensor electronic control system, which automatically diagnoses and refreshes 500 times per second to ensure the accuracy and stability of loading, thus obtaining high-precision test results.

Product Name: MHV-2 Video Measuring Micro Vickers Hardness Tester
Product model: MHV-2
Exhibitor: Beijing Times Peak Technology Co., Ltd.
MHV-2 video measuring microhardness tester is the third generation high-tech product integrating optics, mechanics and electronics. The machine has perfect shape, unparalleled reliability, high flexibility, operability and intuition. It is a new Vickers and Knoop hardness tester which adopts precision mechanical technology, digital image processing technology, photoelectric technology and high-speed signal acquisition and video algorithm technology. The micro Vickers hardness tester for video measurement is controlled by a microcomputer. The measurement of Vickers hardness and Knoop hardness can be selected by soft keys, the intensity of measuring light source can be adjusted, and the holding time of testing force can be preset. The hardness grade HV or HK can be selected by operating the control keys, and the test force, load holding time and light source brightness can be adjusted steplessly. Diagonal length D 1 and D2 can be measured by micrometer eyepiece or video measuring screen, and the hardness value can be displayed on LCD after key input. The hardness image can be visually observed on the video screen, and the operation is simple. The diagonal length of indentation is measured by the panel input, and the hardness value is directly read by the screen, which simplifies the tedious look-up table. Video microhardness tester adopts unique indentation measurement conversion and micrometer eyepiece one-time measurement reading mechanism, which is convenient to use and has high measurement accuracy. You can directly observe the measured indentation and the metallographic structure of the material through the big screen. Reduce the fatigue and error when observing through the eyepiece. It is widely used to measure the microhardness of tiny thin samples and surface infiltrated coatings, and to measure the Knoop hardness of brittle and hard materials such as glass, ceramics, agate and artificial gem. It is an ideal hardness testing instrument for scientific research institutions, factories and quality supervision departments to study and test materials.
