The Mitutoyo 700-128 plastic caliper is a digital caliper with deep throat type jaws for outer diameter (OD) measurements from 0 - 150 mm. Digital LCD characters and durable plastic construction make this caliper suitable in a wide range of settings, including nurseries, medical offices, laboratories, and trade workshops. This caliper has accessible zero-setting and on/off function control buttons and uses the metric measuring system.

The 700-128 has the electrostatic capacitance type linear encoder. It weighs 163 g and measures outer diameter (OD). Its metric system uses a 0.1 mm gradient. The caliper’s length is 235 mm, jaw depth is 80 mm, jaw length is 65 mm, sliding LCD is 60 by 34 mm, and beam width is 16 mm. Range is 0 - 150 mm, resolution is 0.1 mm, and accuracy is rated + or - 0.05 mm. Also included are zero-setting and power on/off function buttons. An alarm alerts the user to low voltage and counting value composition errors. A rolling thumbwheel makes fine adjustments and a thumbscrew locks the scale’s position. Response speed is 1,800 mm/s. The SR44 silver oxide cell battery (part 938882) lasts approximately 2 years with normal use.

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.

Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
