The Mitutoyo 209-113 internal dial caliper gage uses a dial to perform quick comparison measurements between 1.2" - 2.2". It is used together with a ring gauge, setting ring, or micrometer, and takes inside (ID) readings.
An internal dial caliper gage is one of the simplest forms of calipers. It is used for making quick ID measurements. This caliper gage measures indentations, grooves, and hole diameters. The gage has two spring-loaded arms that make point contact with constant measuring pressure. It is a simplified version of a dual scale dial caliper. The dial is circular and has a pointer; it is mounted on a toothed gear track which drives the pointer. The minimum measurement of the dial creates the accuracy of that result. The dial is marked in inches or millimeters and 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 reading errors. Its precise measurements complement the use of the vernier caliper; the dial provides readability and interpolating measurements which most vernier calipers, due to their need for direct observation of both scales, may not provide. The dial caliper gage is used along with a setting ring or micrometer; the moveable bezel is adjusted before use by bringing the zero point to an identified size. This caliper gage utilizes a simple inch measuring dial for ease and speed in comparative ID measurements.
The 209-113 caliper gage has a dial with a white face, weighs 0.18 lbs, measures in inches, and is graduated in 0.001" increments. It has black oxide finished arms with 0.04" diameter steel ball measuring tips and a chrome-plated bezel. Its fixed arms take inner diameter (ID) measurements. It has a dial height of 51 mm and measuring tip lengths 17 mm and 6.8 mm (far side) and 14.5 mm and 4.3 (dial side). Range is 1.2" - 2.2", graduation is 0.001", and throat depth is 3.15".
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, machining, manufacturing, carpentry, and medicine. 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 all 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 dial caliper is used for measuring size differential between two objects, as well. The digital caliper takes the same sort of differential measurements as the dial caliper by zeroing the display at any point along the slide, with an LCD (replacing the dial) that displays a single, easily read value in both English and metric units. Some digital calipers can hold data readings between measurements and send them to data collection devices.
Founded in Tokyo in 1934, Mitutoyo is a leader in the metrology field, producing high-quality measurement products, including mechanical, dimensional gauging products, focusing on micrometers, calipers, indicators, and other measurement tools, as well as output gauges, interfaces, data collectors, and analysis software. Mitutoyo formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, Illinois, with additional locations in the U.S. and Canada.
The Mitutoyo 209-113 is supplied with a fitted carrying case.
