The Fowler 54-860-005-1 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 0.00024"/0.006mm on 4 - 5" 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 work piece, 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. An ABS (acrylonitrile butadiene styrene) housing protects electronic components against impact and provides electrical insulation. This product has a 1 year warranty offered by Fowler Precision. If you experience any problem contact Fowler directly for warranty claims. The micrometer can be set to take absolute or incremental measurements. Absolute measurements provide the total dimension of the work piece. Incremental measurements provide a reading that shows the difference between a set standard and work piece being measured. This type of reading is often used to determine if a work piece 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 Type CR2032 battery (included), and includes a wrench and a fitted case. Micrometers 2" and above include a standard. \.
