The  two dimensional measuring instrument is used for high-magnification optical imaging of the object measured by an optical microscope.  After the CCD camera system sends the enlarged image of the object into the computer, it can efficiently detect the contour and surface shape, size, angle and position of various complex workpiece.  It is applied in quality testing to ensure that all parts are of high quality and conform to safety specifications.

Put the spare parts of the product into the two-dimensional imaging instrument to measure the appearance and size, compare with the appearance and size required by the drawing, and check whether the size and appearance are within the required tolerance range.
