The calibrated Mitutoyo 64PKA076CAL tool kit contains the calibrated Mitutoyo 293-340CAL Digimatic digital micrometer and the calibrated Mitutoyo 500-196-30CAL Absolute Digimatic digital caliper, both suitable for working in harsh workshop conditions. The 293-348CAL micrometer is for taking outside diameter measurements and has a measurement range of 0 to 1" (0 to 25.4mm), resolution of 0.00005" (0.001mm), and an accuracy of + or - 0.00005". The LCD screen displays in inches and metric units. The micrometer's plastic components are oil-resistant and measuring faces are carbide-tipped for durability. This gauge is Ingress Protection certified IP65 for protection against dust and water. Micrometer functions include origin point setting, zero setting, hold, automatic on and off after 20 minutes of idle time, function lock, and an alarm in case of computing error or low-voltage. A ratchet stop helps provide uniform pressure for precise, repeatable measurements. It has a battery life of approximately 1.2 years of normal use.
The 500-196-30CAL caliper is for measuring inside and outside diameters, depth, and step of items. 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. Caliper functions include absolute measurement, incremental measurement, scale contamination alert, and low-voltage alert. This caliper has a battery life of approximately 3.5 years of normal use.
This kit comes with two SR-44 batteries, micrometer wrench, and protective mahogany case. Mitutoyo calibrated tools include a Certificate of Calibration that provides evidence that these tools have been calibrated and are 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.
Micrometers are precision measuring instruments that use a calibrated screw to measure distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.
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.
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.
