Calipers & Micrometers, Tools for Measuring Inside or Outside Dimensions

The Caliper & Micrometer are precision measuring tools that accurately measures internal and external distances of an object such as the thickness of a pipe wall, inside diameter of a tube, or the size of a ball bearing. These instruments are used in many applications by engineers and machinist. Most Calipers have two sets of arms and a depth finding gauge. One set for measuring outside and a second set for the inside. Caliper models are available for inch and metric measurement read manually or using a digital display. The micrometers offered take outside measurements with 1/1000” accuracy.
