A caliper whose legs turn outward so that it can accurately measure inside dimensions, as the inside diameter of a pipe.
Inside calipers are used to measure inside dimensions such as the inside diameter of a tube, while outside calipers are used for measuring outside dimensions such as the outside diameter of a tube or a piece of bar stock. Because the arms on calipers are made of fairly light metal, they may be sprung out of shape quite easily. They require a light touch. The accuracy achieved in making measurements with simple calipers is very much dependent on the machinist.
