The Fowler 54-870 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"/0.004mm provide precise readings and accurate measurements. Carbide measuring faces provide long life and wear resistance. A ratchet thimble applies consistent force for repeatability between users. A jet back and grey enamel finish provide durability and wear resistance.

The LCD has a hold feature that saves the reading for recording. 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. An automatic shut-off feature extends battery life. RS-232 output transfers data to a computer (cable not included). The micrometer requires a CR2032 battery (included), and includes a fitted case.

Micrometers are precision measuring instruments that use a calibrated screw to measure 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.

The Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
