The Mitutoyo 573-282-20 ABSOLUTE snap digital caliper has a spring-loaded mechanism to allow efficient assessment of mass produced parts. This caliper has accessible function control buttons, such as Origin-set, Zero-setting, Power On/Off, Inch/Metric, and Data Output, and uses both inch and metric measuring systems.

The 573-282-20 has the ABSOLUTE electrostatic capacitance linear encoder. It weighs 233 g and has a depth bar. Main scale length is 290 mm, lower jaw depth is 50 mm, upper jaw length is 24.5 mm, upper jaw depth is 20 mm, and beam width is 16 mm. Range is 0 - 6"/0 - 150 mm, resolution is 0.0005"/0.01 mm, and accuracy is rated at + or - 0.001". Measuring force is 7N to 14N. Also included are origin-setting, zero-setting, inch/metric conversion, data output, and power on/off function buttons. A Digital LCD Data Reading Hold function is available with the optional data hold unit (part 959143), sold separately. An alarm alerts the user to low voltage and counting value composition errors. A thumbwheel permits fast and easy measuring and a thumb screw locks the scale’s position. Response speed is unlimited. The caliper has Statistical Process Control (SPC) data output capability for manufacturing quality control. It outputs data using a serial data interface to a computer or other dedicated recording device using SPC cable with data switch (959149 or 959150, depending on cable length). The SR44 silver oxide cell battery (part 938882) lasts for approximately 3.5 years of normal use and is recommended to maintain constant voltage levels.

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 also for measuring size differential between two objects. 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.

The Mitutoyo 573-734 ABSOLUTE Digimatic blade type digital caliper uses Mitutoyo’s ABSOLUTE linear encoder technology and has thin, blade type jaws to fit into small grooves for hard-to-obtain outside (OD) measurements. This caliper has accessible function control buttons, such as Origin-set, Zero-setting, Power On/Off, Inch/Metric, and Data Output, and uses both inch and metric measuring systems. Although identical to dial and vernier calipers in its ability to make precise measurements, the digital caliper’s LCD increases reading reliability.

The 573-734 has the ABSOLUTE electrostatic capacitance type linear encoder. It weighs 168 g and has a depth bar. Outside (OD) jaw measuring faces are carbide-tipped. Range is 0 – 6”/0 to 150 mm, resolution is 0.0005”/0.01 mm, and accuracy is rated + or - 0.001”. Also included are Origin-setting, Zero-setting, Inch/Metric, and Power On/Off automatic shutoff function buttons. This caliper meets standard IP67 for protection against dust and temporary submersion in water. 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. The caliper has Statistical Process Control (SPC) data output capability; it outputs data using a serial data interface to a computer or other dedicated recording device using SPC cable with data switch (05CZA624 or 05CZA625, depending on cable length). The SR44 silver oxide cell battery (938882) lasts approximately 3.5 years with normal use and is recommended to maintain constant voltage levels.
