Mitutoyo 468-267 Electronic Inside Micrometer 1.0-1.2 in IP65

Product Description

The MITUTOYO 468-267 is a 3-point electronic inside micrometer designed for precise internal bore measurement across a range of 1.0000 to 1.2000 inches (25.40 mm minimum). Resolution is 0.00005 inches with a stated accuracy of 0.00015 inches, making it appropriate for high-tolerance machining, inspection, and quality-control work. The unit carries an IP65 ingress protection rating, meaning it resists dust and low-pressure water jets during use on the shop floor. A ratchet stop thimble provides consistent measuring force, and a titanium nitride finish adds surface durability. Licensed machinists, tool-and-die technicians, and metrology professionals are the primary users of this instrument.

The 468-267 is suited for residential and commercial machine shops, manufacturing facilities, and inspection departments where bore diameter must be confirmed to tight tolerances. Three contact points allow single-handed insertion and a self-centering measurement, which reduces operator error compared to two-point instruments. The large LCD display with a character height of 7.5 mm is readable under typical shop lighting conditions. Data output capability allows the instrument to connect to SPC data-collection systems or compatible printers for documented inspection records.

Key Features

• Measurement range: 1.0000 to 1.2000 inches (25.40 mm minimum)
• Resolution of 0.00005 inches for high-precision bore inspection
• IP65-rated housing resists dust and water ingress on active shop floors
• 3-point self-centering contact design reduces operator-induced error
• Ratchet stop thimble delivers consistent, repeatable measuring force
• Data output port supports SPC and external data logging
• Titanium nitride finish for improved wear and impact resistance

Compatibility

Designed as a precision bore-measurement instrument for use in general metrology and inspection applications where an inside micrometer in the 1.0000 to 1.2000 inch range is specified.

Installation Notes

This instrument is a handheld measuring tool, not an installed component; no permanent installation is required. Calibration should be verified against a known standard before use and at intervals required by the applicable quality system. Handle with clean, dry hands or cotton inspection gloves to prevent thermal expansion from body heat and to protect the titanium nitride contact surfaces. Store in the supplied plastic case when not in use to protect the LCD and contact points.
