摘要：Disclosed is a bore measurement unit having an elongate main body with firstand second ends. A first adjustment mechanism is disposed near the first end and asecond adjustment mechanism is disposed near said second end. The adjustment
mechanisms expand or contract, through triangulating arms, to relative diameters, suchthat when the unit is inserted into a hollow bore it may be centered therein. A measuringportion of the unit measures the internal diameter of the bore. The measuring unitincludes at least one sensor and preferably takes more than three readings at eachdistance of insertion to formulate a best fit circle of the inner bore diameter.
