The Mitutoyo 505 series dial caliper uses a combination of a vernier scale and a dial with a pointer that travels one rotation for each 0.2 measured to perform precise outside dimension (OD), inside dimension (ID), depth, and step measurements.

The dial caliper has a fixed (main) scale and a movable dial, unlike the vernier caliper which has a second, movable vernier scale. The dial is circular and has a pointer; it is mounted on a toothed gear track which drives the pointer. As the dial moves over the main scale rule, the pointer rotates once to give the additional fractional reading. The second measurement is added to the main scale reading to obtain a final result accurate to the smallest graduation marked on the dial. The main scale and dial are marked in inches. The dial can be rotated beneath the pointer to measure size differential between two objects. The dial caliper is easier to read than the vernier caliper, thus safeguarding against user reading errors. Its standard of precise measurement complements the use of the vernier caliper; the dial provides an ease in reading and interpolating measurements which most vernier calipers, due to their need for direct observation of both scales, may not provide.

The dial uses a rack-and-pinion mechanism and is mounted on a gear track where each tooth equals one quarter of the dial revolution, and four teeth equal 0.2. The smooth-moving dial is graduated to 0.001 and offers gear train shock protection. A thumbwheel permits fast operation with one hand. A clamping screw controls scale movement and a dial calibration lock holds the sliding jaws position. The caliper is made of hardened stainless steel construction with titanium nitride (TiN) coating on the beam wear surface helps extend caliper life. Two sets of jaws provide four-way measurement capability: outside dimension (OD), inside dimension (ID), depth, and step, where the butt end of the fixed jaw measures one end of a work piece before its upper/lower or inner/outer steps are measured.

Calipers measure the distance between two opposing sides of an object. They make inside, outside, depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, and machining. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial, and digital calipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw, and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The digital caliper takes a differential by zeroing the display at any point along the slide, with an LCD that displays a single value in English and/or metric units.

The Mitutoyo 500-196-30 digital caliper has a 0 to 6" (0 to 150mm) measuring range with 0.0005" (0.01mm) increments for precision and an advanced onsite sensor (AOS) electromagnetic inductive sensor for resistance to dirt, oil, and water. Its digital readout LCD shows inch or metric units for versatility, and allows either absolute or incremental measurement readings. The electronic caliper measures inside, outside, depth, and step values for versatility and includes a protective case and SR44 silver oxide battery.

Digital 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 take inside, outside, and step measurements. 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 with gearless precision to take measurements. The reading is electronically generated and displayed on a digital, high-resolution screen as a single value. Digital calipers can take differential measurements, which are used to determine the difference in measurements between two objects, by zeroing the display at any point along the scale. Some digital calipers can switch between standard and metric units, and some can output readings to a computer or printer for recording measurements. Compared to dial calipers, digital calipers provide measurements that are faster, easier, and more error-free, but they are more fragile mechanically and electronically, and do not resist coolant well. Vernier calipers are more durable than digital calipers because they do not have internal moving parts, but they can be more difficult to read. Digital calipers are commonly used in fields such as metalworking, mechanical engineering, machining, carpentry, and medicine.
