Top 9 012 Range Calipers

The Mitutoyo 500-197-30 digital caliper has a 0 to 8″ (0 to 200mm) 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.

Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. The company, founded in Tokyo in 1934, formed Mitutoyo America Corporation in 1963 with headquarters in Aurora, IL.

The Mitutoyo ABSOLUTE 500 series caliper is a Digimatic digital caliper that is made of durable hardened stainless steel and uses Mitutoyo’s ABSOLUTE linear encoder technology, which allows you to “set and forget” the origin and measure in awkward or difficult locations.

This digital caliper has LCD readout and function control buttons on the caliper face, including Origin to set and retain the original measuring point, and Zero/ABS (Absolute Scale) to zero-set the LCD display. It uses the metric measuring system.

Although identical to dial and vernier calipers in its ability to make precise measurements, the digital caliper also has an LCD, which clearly shows values and increases reading reliability over the other types, and reflects all ABSOLUTE system activities. The Absolute Scale (ABS) function tracks the origin point you set, even after shutoff. Once on again, the caliper can immediately start measuring, without zero resetting or concern of overspeed errors. The LCD can be “zeroed out” before making and comparing incremental measurements without having to subtract the first measurement from the second.

The calipers use the ABSOLUTE electrostatic capacitance linear encoder which helps prevent overspeed errors. They measure outer diameter (OD), inner diameter (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. LCD Resolution is 0.01mm. Also included are origin-setting, zero-setting, and on/off automatic shutoff function buttons. A Digital LCD Data Reading Hold function is available with the optional Data Hold Unit (sold separately). An alarm alerts the user to low voltage and scale contamination and counting value composition errors. A rolling thumb wheel makes fine adjustments and a thumb screw locks the scale’s position. Response speed is unlimited. Each caliper includes, and is powered by, one SR44 silver oxide cell battery that lasts approximately 3.5 years with continuous 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, 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 530 series vernier caliper has two sets of jaws and a depth bar for four-way measurement in inch and metric units of outside dimension (OD), inside dimension (ID), step, and depth, for applications where the highest accuracy is required, especially in scientific research and in industries where parts must fit exactly.

The caliper has a dual vernier scale, with an upper scale measuring in inches and a lower scale measuring in millimeters. A 14-degree vernier face angle improves visibility and helps prevent parallax error in measurement reading. The caliper’s two sets of jaws provide the capability to make OD and ID measurements, as well as step measurements, 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. A depth measuring blade with rounded edges provides the ability to make depth measurements. The scales are raised to slide easily and protect the graduation markings. A thumbwheel permits fast and easy measuring. A clamping screw on the upper scale rotates to control scale movement and locks to hold the sliding jaw’s position. The caliper is made of hardened, corrosion-resistant stainless steel with a satin chrome finish that helps reduce glare. The caliper meets Federal Accuracy Specifications GGG-C-111B.
