The Fowler 54-815 series digital outside micrometer has a flat anvil/spindle pair, a choice of measuring range, an LCD with an inch/metric switchable resolution, and is designed for general purpose measuring. A switchable resolution of 0.00005" and 0.001mm, and an accuracy of 0.00016" provide precise readings and accurate measurements. Carbide measuring faces provide wear resistance. The ratchet-stop thimble provides an audible sound and stops turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The steel construction housing provides durability and is Ingress Protection (IP) certified IP54 for protection against dust and water. The LCD has a hold feature that saves the reading for recording and can be set to zero at any spindle location. The micrometer can be set to take absolute or incremental measurements. Absolute measurements provide the total dimension of the workpiece. Incremental measurements provide a reading that shows the difference between a set standard and workpiece being measured. This type of reading is often used to determine if a workpiece falls within tolerance levels. A built-in clock logs the time measurements are taken and an automatic shut-off feature extends battery life. RS-232 output transfers data to a computer (cable not included). The micrometer requires a Type 357 battery (included), and includes a wrench and a fitted case. Micrometers 2" and above include a standard.

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: outsi...
