Mitutoyo 103 Series Standard Outside Micrometer

The Mitutoyo OM-100 Standard Outside Micrometer 75-100 mm Measuring Range 1994781 is a fundamental precision measuring instrument utilized extensively in engineering, manufacturing, and metrology. Its primary function is to accurately measure the external dimensions of objects with exceptional precision and reliability. This versatile instrument serves as a cornerstone in dimensional analysis, ensuring compliance with specified tolerances and contributing to enhanced product quality. The standard outside micrometer comprises a C-shaped frame with a stationary anvil and a movable spindle. The spindle is equipped with a precision-ground measuring face at its tip. To perform a measurement, the object to be measured is placed between the anvil and the spindle, and the ratchet or thimble is rotated to move the spindle towards the object, causing the measuring face to make contact with the external surface. The micrometer's sleeve is finely graduated, while the rotating thimble features a Vernier scale or a digital counter, providing additional decimal places to read the measurement accurately. This dual-scale system allows for precise readings to be taken and is renowned for its high measurement resolution. Proper usage and handling are essential to maintain the accuracy of the standard outside micrometer. Regular calibration against certified reference standards is crucial to verify its measurement integrity. Additionally, periodic maintenance, such as cleaning of the measuring surfaces and lubrication of moving parts, is observed to ensure consistent and reliable measurements.
