Dimensional Measurement is the way we quantify the size and shape of parts, this involves the measurement of length, angles as well as flatness and straightness.  Precision measuring equipment including digital and electronic tools such as micrometers, blade micrometers, combination sets, comparators, depth micrometers, dial indicators, flange micrometers, gage block sets,  plug gage, ring gauges,  screw thread micrometer, Vernier caliper, Vernier height gauge, proportional dividers, hardness surface testing equipment (durometer), Borescopes, Surface plates.
