A bore gage measures inside hole diameter with high accuracy. The controller can either turn a knob or release a trigger to extend pieces outward until the wall perimeter is touched by each contact. A bore gage is usually chosen by categorizing its precision measurement range, depth, accuracy requirements, and the number of contacts. A bore gage can have interchangeable measuring heads, different diameters, and extensions for depth, depending on their usage. A bore gage can also have electronic displays, micrometer-type vernier scales, or a dial that is similar to an indicator.
Calipers provide a large measurement range, flexibility and accuracy up to 0.001.” These tools typically measure outside, inside, depth, and step dimensions. Available in digital, dial, and vernier versions.
A depth gage can vary in form, complexity, cost and accuracy. The most accurate depth gages are a depth micrometer and a dial indicator depth gage. Less complex and precision measurement tools, such as rule gages and combination rule gages, are also available.

A digital or dial indicator is a precision measurement gage that shows movement visually, typically in very tiny increments. These are often used on fixtures that require repetitive inspection or adjustments on a machine. OCS Technologies offers a variety of each of the major classes in Dayton: mechanical dial, electronic display, lever style test and back plunger. Each type has its own unique strengths. Electronic indicators can output data, while analog dial indicators are easy to read and understand for anyone. Resolution varies from 0.001″ to 0.00005″.
