    CCD Image automatic Measurement Software

    The measurement and control of the system is to use a high-resolution image device, the

    indentation will be clearly displayed on the computer screen.

    The hardness of the test indentation is automatically measured by the signal conversion software.

    Depth and gradient curves can be drawn for fixed-point and continuous testing.

    Support the operating systems of WIN9X, WINNT, WIN2000, WIN XP and so on.

    It can be used to test in micro Vickers, Knoop, Carburizing layer and so on.

    Hardness values can be automatically converted in many forms.

    High or low power objective lenses can be chosen as required.

    Image clarity: > 540 lines. The contrast and brightness of the image can be adjusted.

    Image files and data files can be opened and stored separately, printing, etc.

    Data files and image files can be viewed at any time. The data files are printed in the form of tables

    and curves.



    It can be used to continuous test of reading indentation after continuous loading, and can be

    used to carry out the successive experiments of each loading and reading indentation.

    The ccd camera and video line are used to directly observe and measure indentation on the

    display, and the accuracy of the measurement is high with the mouse.

    For setting test conditions, the display results can be clearly and quickly operated and displayed.

    By means of measuring software, the computer can be used to operate conveniently, and the

    single point measurement can be used to measure multi-point and statistical data at random.

    The interval between two or more measuring points can be used to measure the depth of

    seepage layer in X or Y directions, and the data can be measured statistically.

    According to the judgment value (such as 550), the depth of seepage layer is calculated automatically.

    Statistical calculation, conversion, display curve, judging whether qualified or not, etc. The length and

    angle of parts can be measured, and the graphics can be saved and printed. It can be used as a small projector.
