This section includes a wide array of instrumentation, tools, equipment and accessories used for a variety of applications. Calipers are used for dimensional measurement to measure diameter and depth, or replicate a measurement from one space to another. Vernier calipers, digital, and dial calipers are common caliper types.Tools and equipment that are used as common measuring tools in dimensional measurement include micrometers. Outside micrometers are precision measuring instruments that use a calibrated screw to measure the length, width, or outside diameter of an object. Inside micrometers measure interior distances on a workpiece, such as a span between two edges, or the diameter of a circle or hole. Micrometers have inch or metric measurement. Test, Measure, and Inspect instrumentation is commonly used in science, engineering, machining, industrial, health, and educational applications.
