Dial calipers are measuring instruments commonly used for inspection in manufacturing to provide the precise measurements of an object. A pair of jaws attached to a long beam with a marked scale is used to measure inside, outside, and step measurements in standard or metric units. An additional depth probe slides along the beam to take depth measurements. One jaw is fixed to the end of the scale, while the other jaw slides along it to take measurements. A circular dial indicator is fixed to the movable jaw on a toothed gear rack that transfers movement of the jaws to the dial needle. The base measurement is taken from the long beam, which provides the initial whole measurement in inches or centimeters, and added to the dial reading, which provides fractional measurements in inches or millimeters. A locking mechanism provides the ability to take differential measurements for determining the difference in measurements between two objects. Compared to digital calipers, dial calipers are more durable, but are more susceptible to shock damage and prone to getting dirt in the gears, which can cause accuracy problems. Vernier calipers are more durable than dial calipers because they do not have internal moving parts, but they can be more difficult to read. Dial calipers are commonly used in fields such as metalworking, mechanical engineering, machining, and carpentry.
