Abstract
A metrological instrument configured to measure diameters comprises one or more guide rails, a plurality of clamping blocks configured to removably or releaslably securely locate the blocks on the one or more guide rails, and also configured to removably or releaslably securely clamp a measurement arm substantially normal to the one or more guide rails. A displacement transducer, such as a dial indicator or a digital indicator, may be disposed at an end of one or more of the measurement arms for determining a displacement, relative or absolute, between the measurement arms. To provide the required measurement accuracy, precision, and repeatability, the instrument may be configured with carbon fiber reinforced composite guide rails, and/or measurement arms.
