Fowler 54-860-103-1 Electronic Outside Micrometer Set

Product Description

The FOWLER 54-860-103-1 is an electronic outside micrometer set covering a measurement range of 0 to 3 inches (0 to 75 mm). It delivers a resolution of 0.001 mm and an accuracy of 0.0001 inches, making it well suited for precision dimensional inspection in manufacturing, machining, and toolroom environments. The set features a friction thimble for consistent measuring pressure and carries an IP54 ingress protection rating, meaning it resists dust and splashing water during normal shop use. A factory calibration is included. Metrology technicians, machinists, and quality control professionals are the primary users of this instrument.

This micrometer set is designed for outside diameter and thickness measurements across a 0 to 3 inch range, suitable for use in machine shops, production lines, and inspection departments. The electronic readout eliminates manual interpolation and speeds up measurement cycles. The IP54 rating makes it appropriate for light wet-cutting or coolant-mist environments where some moisture exposure is expected.

Installation Notes

Handle and store precision measuring instruments away from heat sources, magnetic fields, and direct sunlight to maintain calibration integrity. Before use, clean the measuring faces with a lint-free cloth and verify the zero setting. Periodic recalibration against a certified gauge block is recommended per your facility quality plan. No power tools or trade licensing are required for instrument setup.
