Digital Caliper
Home > Instrumentation, Equipment, and Facilities > Dimensional Data and Measurement Tools > Digital Caliper
Digital calipers are used to measure the distance between two opposing sides of an object. It may be an inner dimension (such as the diameter of a hole) or an external diameter (such as the thickness of an object). The analog versions of calipers have a continuous dial with a needle from which to read results; digital versions provide an LCD display. Digital calipers also have a scale for manual use in the event of battery failure.
