Inside micrometers are typically used to measure interior diameter, as in a hole. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. There are three types of micrometers: outside, inside, and depth. Micrometers are typically used in manufacturing, machining, and mechanical engineering. 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 precision measuring instruments that use a calibrated screw to measure small distances. A spindle lock helps provide secure locking of the measurement position. The spindle and anvil have flat measuring faces and are carbide-tipped for wear resistance. The vernier scale on the thimble and sleeve is graduated to 0.01mm, with a satin chrome rust- and glare-resistant finish. The micrometer’s frame has a baked enamel finish for protection and durability. The Mitutoyo 103-137 Outside Micrometer has a vernier scale in metric units for taking precise outside diameter (OD) measurements, and a ratchet-stop mechanism for uniform pressure during adjustment.

The friction thimble models allow for constant-force measurement for single handed operation. A ratchet-stop mechanism on the Mitutoyo 103-137 provides uniform pressure on a workpiece for precise, repeatable measurements.

The Mitutoyo 103-137 Outside Micrometer is ideal for measuring metal and non-metal workpieces.

The Mitutoyo 103-137 Outside Micrometer series 103 features either a ratchet stop or friction thimble that applies constant measuring force on a workpiece for exact repetitive readings.
