Mitutoyo 422-332-30 Electronic Blade Micrometer 2-3 in

Product Description

The MITUTOYO 422-332-30 is an electronic blade micrometer with a measurement range of 2 to 3 inches, designed for precision measurement in tight grooves, keyways, and narrow slots that standard micrometers cannot reach. It delivers a resolution of 0.00005 inches and an accuracy of 0.000150 inches, making it suitable for high-tolerance inspection work. The satin chrome finish reduces glare during use. This instrument is installed and operated by machinists, quality control technicians, and tool-and-die professionals working in manufacturing, fabrication, and maintenance environments.

This micrometer is built for applications where blade-style anvil and spindle geometry is required to access recessed features. The blade thickness of 0.0295 inches and blade depth of 6.50 mm allow measurement in narrow channels and undercut profiles. A ratchet thimble provides consistent measuring force for repeatable readings. The non-rotating spindle prevents part marking and ensures stable contact during measurement. It is well suited for both shop-floor use and inspection bench work in precision manufacturing settings.

Key Features

• Electronic readout with 0.00005-inch resolution for high-precision measurement
• Blade thickness of 0.0295 inches enables access to narrow grooves and keyways
• Non-rotating spindle protects workpiece surface and stabilizes contact
• Ratchet thimble delivers consistent, repeatable measuring force
• IP54 water resistance rating provides protection against coolant splash and dust
• Includes SR44 battery and plastic storage case

Compatibility

Designed as a precision measurement instrument for general machining and inspection applications requiring a 2 to 3 inch measurement range with blade-style geometry.

Installation Notes

This instrument requires no installation but should be calibrated against a known standard before use in critical inspection work. Keep the measuring faces clean and free of chips or coolant residue before each measurement. Store in the included plastic case when not in use to protect the blade anvil and spindle from damage. Battery replacement uses a standard SR44 cell.
