Mitutoyo 293-961-30 Electronic Outside Micrometer Set 4 Piece

Product Description

The MITUTOYO 293-961-30 is a 4-piece electronic outside micrometer set covering a measurement range of 0 to 4 inches (0 to 101.6 mm). Each micrometer in the set delivers a resolution of 0.001 mm and achieves accuracy of 0.00005 inches over the 0 to 3 inch range, tightening to 0.0001 inches over the 3 to 4 inch range. The set is rated IP65 for dust and coolant resistance, making it well suited for shop-floor measurement environments. Carbide measuring faces extend service life under repeated use. A ratchet stop thimble provides consistent measuring force across readings. Data output capability allows integration with SPC data collection systems.

This set is used in precision machining, tool and die, quality control, and metrology applications where accurate outside diameter and thickness measurements are required. The 4-piece configuration covers the full 0 to 4 inch range in 1-inch increments, eliminating the need to purchase individual micrometers separately. It is appropriate for both shop-floor production inspection and inspection room use. Licensed machinists, tool and die makers, and QC technicians are the primary users. The included case and standard bar support organized storage and periodic calibration verification.

Key Features

• IP65-rated ingress protection resists dust and coolant splash during shop-floor use
• Carbide measuring faces provide extended wear resistance compared to standard steel faces
• Ratchet stop thimble ensures consistent measuring force for repeatable readings
• Data output port supports direct connection to SPC or data logging systems
• Rotating spindle design for standard outside micrometer technique
• Includes carrying case and standard bar for storage and reference calibration

Compatibility

Designed as a standard 4-piece outside micrometer set covering 0 to 4 inches in 1-inch increments; compatible with SR44 replacement batteries and standard micrometer accessories.

Installation Notes

Outside micrometers require no installation but should be zeroed or verified against the included standard bar before use. Store in the provided case to protect measuring faces and prevent thermal distortion from handling. Calibration should be performed by qualified metrology personnel in accordance with applicable ISO or ANSI measurement standards. Do not expose the instrument to immersion or high-pressure washdown despite the IP65 rating.
