Top 10 Caliper 08 Ninja 250

The calibrated Mitutoyo 500-196-30CAL Absolute Digimatic caliper is for measuring inner/outer diameters, depth, and step of items in harsh workshop conditions. This caliper has a measurement range of 0 to 6″ (0 to 150mm), resolution of 0.0005″ (0.01mm), and an accuracy of + or – 0.001″. The LCD screen displays in inches and metric units. This unit has a roller and Absolute electrostatic capacitance type linear encoder for accurate measurements. Functions offered by this model include absolute measurement, incremental measurement, scale contamination alert (provided by the Advanced Onsite Sensor (AOS), and low-voltage alert. Mitutoyo calibrated tools include a Certificate of Calibration that provides evidence that the tool has been calibrated and is within allowable error specifications. Mitutoyo calibrated tools are certified by Mitutoyo’s American Association for Laboratory Accreditation-accredited calibration laboratory (A2LA Certificate #750-01) to the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) 17025 International Standard for testing and calibration laboratories.

This caliper has a battery life of approximately 3.5 years of normal use. This unit comes with an SR-44 battery and a fitted, plastic case.

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.

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 Fowler 54-554-630 digital outside dimension (OD) caliper measures 0 to 6″/0 to 150mm with 0.01″, 0.1mm, or 1/64″ accuracy and 0.01″, 0.1mm, or 1/64″ resolution, and has a plastic electronic housing with stainless steel arms and hardware, an LCD readout, zero-setting capability, a hold feature, and is spring loaded. This caliper measures OD for hole diameters and groove and tube thicknesses. The digital, single-value readout LCD shows inches, in decimals or fractions, or metric for versatility when measuring. The hold feature freezes the display for later viewing. The unit also has a zero setting for taking intermediate or differential measurements. The knurled lock nut holds the spring-loaded sliding jaw in position and helps ensure a consistent measurement. The caliper arms and hardware are constructed of stainless steel for durability. The 2″/5cm diameter electronic housing is constructed of plastic. The caliper uses a 3V CR2032 battery (included) for approximately one year of use. An automatic shut-off feature turns the caliper off after four minutes to prolong battery life. The unit also comes with a plastic case and instructions.

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 that 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. Caliper gages are used in production settings where specific diametrical or thickness measurements must be repeated frequently with precision and accuracy. 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.

The Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.

The Mitutoyo 050084-10 depth base attachment has a 4″ base length and is suitable for use with Mitutoyo 4 to 8″ (100 to 200mm) vernier and dial calipers (sold separately). The knurled locking clamp holds a caliper securely. The base is made of steel and the measuring face is ground for flatness. This depth base is suitable for precise measurement in a variety of manufacturing, machining, and mechanical engineering applications.

Depth gauges are precision measuring instruments used to determine the depth of any shape that has a step, groove, or slot. These gauges often take the form of sliders that travel on a measuring beam or rods, are moved to position by hand, and then adjusted with a calibrated screw. The base of the gauge rests at the top of the shape whose recession is to be measured, while the beam or rods extend to the bottom of the recession to determine the measurement. Gauge position is read from a graduated scale, dial, counters, or an electronic display.
