Mitutoyo 293 Series Quantumike Digimatic Micrometer

The Mitutoyo MDE-25MX Measuring Range 0-25 mm Quantumike (Digimatic Micrometer) 26218526 is a precision measuring instrument used to obtain highly accurate measurements of length, thickness, and diameter. It is widely employed in various industries, including engineering, manufacturing, metrology, and scientific research, where precise measurements are critical for quality control and process optimization. The construction of a micrometer consists of a rigid C-shaped frame with a calibrated screw attached to its interior. The screw has finely etched threads that mesh with the thimble, allowing for precise rotational movement. The thimble is marked with graduations, and each line corresponds to a specific measurement increment, typically 0.01 mm or even smaller. Additionally, a sleeve surrounds the screw, featuring a scale with larger markings that correspond to the complete rotations of the thimble. To use the micrometer, the object being measured is placed between the anvil and the spindle, which are the flat and parallel measuring surfaces located at the ends of the micrometer. The thimble is then rotated to move the spindle towards the object, ensuring a light but definite contact. The user continues rotating the thimble until the object is securely held, and the measurement is obtained by reading the aligned lines on the sleeve and thimble scales. The precision of the micrometer allows measurements down to thousandths of a millimeter or even smaller, depending on the instrument's resolution. Micrometers are available in various types, such as outside micrometers used for measuring external dimensions, inside micrometers for internal measurements, depth micrometers to gauge the depth of holes, and digital micrometers equipped with electronic displays for easier reading.
