Fowler 54-860-301-0 Electronic Disc Micrometer 0-1 Inch

Product Description

The FOWLER 54-860-301-0 is an electronic disc micrometer designed for precision measurement in demanding shop and field environments. It covers a measurement range of 0 to 1 inch with a resolution of 0.00005 inch and a rated accuracy of 0.00016 inch, making it suitable for high-tolerance inspection work. The disc-style anvil - 0.7874 inches (20.00 mm) in diameter with an edge thickness of 8.89 mm - allows measurement of features that a standard flat anvil cannot reach, such as grooves, keyways, and narrow slots. The ratchet stop thimble ensures consistent measuring force on every reading. Licensed metrologists, quality technicians, and precision machinists are the primary users of this instrument.

This micrometer is well suited for production inspection, tool-and-die work, and quality control applications where groove width, land thickness, or recessed feature dimensions must be verified repeatedly and reliably. The IP54 water-resistance rating means the instrument tolerates splash exposure and airborne particulates, making it appropriate for machine-side use in typical manufacturing environments. Data output capability allows integration with statistical process control systems or compatible data loggers for recorded measurement workflows.

Key Features

• 0 to 1 inch measurement range with 0.00005 inch resolution for fine tolerance work
• Disc anvil at 0.7874 inches diameter enables measurement of grooves, slots, and recessed features
• IP54-rated water and dust resistance for machine-side durability
• Ratchet stop thimble delivers repeatable, controlled measuring force
• Data output port supports connection to SPC systems and compatible data collection devices
• Powered by a 357 battery; includes protective case

Compatibility

Designed as a direct-use electronic disc micrometer for inspection applications requiring a 0 to 1 inch range with a disc-style anvil; confirm anvil geometry and data output interface compatibility with existing fixtures or data collection equipment before installation into a gauging station.

Installation Notes

Calibration and setup should be performed by a qualified metrologist or instrument technician following the manufacturer documentation included with the unit. Prior to first use, verify the battery is seated correctly and zero the instrument against a clean, appropriate standard. Protect the disc anvil edge from impact during storage and transport - store in the included case. Do not submerge the instrument; IP54 rating covers splash and dust only.
