Mitutoyo 129-127CAL Depth Micrometer with Calibration, Inch, Ratchet Stop, 2.5 x 0.63″ Base, 0-4″ Range, 0.001″ Graduations, +/-0.00015″ Accuracy

The calibrated Mitutoyo 129-127CAL micrometer is for measuring the thickness of items such as sheet metal, paper, plastic, and rubber parts. The micrometer has a measurement range of 0 to 4.0″, graduations of 0.0001″, and an accuracy of + or – 0.0002″. This model has a standard scale in inches. This item has a ratchet stop to help provide uniform pressure for precise, repeatable measurements. The measuring rods can be locked for stability. This model comes with four flat-tipped, 4mm diameter, interchangeable extension rods for measuring different ranges. 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 micrometer has a satin chrome finish on the sleeve and thimble for corrosion-resistance and visibility. This unit comes with a fitted, plastic case.

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.
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.
