摘要： A measuring device (20), having an outer base arm (22), an end arm (24), a plurality of intermediate arms (26, 28, 30, 32, 34), and a sequential deployment assembly (36), is utilized to take internal measurements with a high degree of accuracy. The sequential deployment assembly (36) operates to sequentially deploy the arms (24-34) as each arm reaches a fully deployed position. A longitudinal serial of graduations is operatively associated with the arms for an (24-34) operator to read distances therefrom.
