Description

The Fowler 54-860 series digital outside micrometer has a ball anvil/spindle pair, a choice of measuring range, and an LCD with an inch/metric switchable resolution for measuring the inside and outside diameters of sleeves, collars, tubing, and other curved and cylindrical surfaces. The ball anvil and spindle contact the curve at a single point, providing accurate measurements. Carbide measuring faces provide wear resistance. A switchable resolution of 0.00005″ and 0.001mm, and an accuracy of 0.00016″/0.004mm on 1 to 2″ micrometers provide precise readings and accurate measurements. A friction thimble provides smooth and quiet operations, and is suitable for one-handed operation. Friction-style thimbles stop turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The insulated steel 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. 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. RS-232 output transfers data to a computer (cable not included). The micrometer requires a Type 357 battery (included), and includes a fitted case. Micrometers 2″ and above include a standard.

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.
