Mitutoyo 113-102 Limit Micrometer, Ratchet Stop, 0-25mm Range, 0.01mm Graduation, +/-0.003mm Accuracy

The Mitutoyo 113 series limit micrometer has two sets of spindles and anvils for Go/No-Go (GO/NG) inspection of outside dimensions (OD) within tolerance limits. Each spindle and anvil set has a vernier scale in metric units for taking precise outside diameter (OD) measurements, and a knurled friction thimbles that help provide quick adjustment capability. The micrometer’s frame has a baked enamel finish for protection and durability. The vernier scales on the thimble and sleeve are graduated to 0.01mm, with a satin chrome rust- and glare-resistant finish. The spindles and anvils have flat measuring faces and are carbide-tipped for wear resistance. Spindle locks help provide secure locking of the measurement positions.

Micrometers are precision measuring instruments that use a calibrated screw to measure small 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 systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
