SPI 13-808-1 Electronic Ball Anvil Micrometer 0-1 Inch

The SPI 13-808-1 Electronic Ball Anvil Micrometer measures external dimensions from 0 to 1 inch with a 0.00005 inch resolution, delivering fast, digital readings on a clear display that reduce guesswork and expedite accuracy checks in busy inspection workflows. Its ball anvil design supports precise contact on small, curved features where a flat anvil could distort results, making it suitable for measuring outside diameters, thicknesses, and step features on miniature components, tools, or assemblies with limited access. The instrument is built with an IP65-rated enclosure, providing protection against dust and water jets so it can perform reliably in standard shop environments where splashes or dust are present. With the digital readout, users can quickly verify tolerances and maintain consistent results across repeated measurements, supporting accurate quality control and dimensional checks in precision machining and assembly tasks that require reliable external measurements.
