A kind of alternate form measuring equipment, comprising: host, comprising opening up body jaggy and its interior master component, microprocessor and first connection unit of the master component comprising the first support plate and thereon； Mould group is measured, comprising being equipped with the panel of measurement connector and setting the second support plate of what panel, the second support plate is electrically connected with the second connection unit of measurement unit, measurement connector and corresponding first connection unit. When panel can group unload corresponding positioning what notch when, the second connection unit simultaneously can group be electrically connected the first connection unit of what with unloading, communicate measurement unit electrically each other with microprocessor. With can depending on measure need corresponding to measure mould group can group organize merging with unloading be electrically connected what host, reach alternate form measuring function, have effects that not waste and cost can be reduced.一種替換式量測裝置，包括：主機，包含開設有缺口的機體及其內的主控組件，主控組件包含第一載板及其上的微處理器和第一連接單元；量測模組，包含設有量測連接器的面板和設於面板的第二載板，第二載板電性連接有量測單元、量測連接器和對應第一連接單元的第二連接單元。當面板可組卸地對應定位於缺口時，第二連接單元同時可組卸地電性連接於第一連接單元，使量測單元與微處理器彼此電性相通。以能視量測需要將相應的量測模組可組卸地組合並電性連接於主機，達到替換式量測功能，具有不浪費且能降低成本的功效。
