Mitutoyo 122-151-10CAL Blade Micrometer 1 in Mechanical

Product Description

The MITUTOYO 122-151-10CAL is a mechanical blade micrometer designed for precision measurement in tight grooves, slots, keyways, and other hard-to-reach features where standard anvil micrometers cannot reach. It measures up to 1 inch with an accuracy of 0.00015 inches and a graduation of 0.0001 inches, making it suitable for high-tolerance inspection work. The carbide-tipped blade and spindle resist wear for long service life. A ratchet thimble delivers consistent measuring force, reducing operator-to-operator variation. An IP54 water resistance rating provides protection against dust and splash exposure in shop environments. NIST traceability certification is included, supporting documented calibration requirements in quality-controlled settings. Licensed metrologists, machinists, and quality technicians are the primary users of this instrument.

This blade micrometer is suited for precision measurement tasks in manufacturing, machining, and inspection environments where narrow features must be measured accurately. Typical applications include measuring slot widths, keyway depths, groove diameters, and thin-walled sections that a standard micrometer anvil cannot contact cleanly. The 0.4 mm blade thickness and 8 mm blade depth allow access into very confined geometry. The satin chrome finish reduces glare under shop lighting. This instrument is appropriate for both production floor use and laboratory or inspection bench settings.

Key Features

• Blade thickness of 0.4 mm and blade depth of 8 mm for access to narrow grooves and slots
• Carbide blade and spindle for wear resistance and extended service life
• Ratchet thimble provides repeatable, consistent measuring force
• IP54 rated for dust and splash resistance in shop environments
• NIST traceability calibration certificate included for quality system compliance
• Satin chrome finish with enamel accents; includes plastic storage case

Compatibility

Designed as an OEM-style precision instrument in the Mitutoyo Series C-2 blade micrometer line, suitable for standard 0 to 1 inch measurement range applications requiring blade-style anvil geometry.

Installation Notes

This instrument is used by machinists, metrologists, and quality control technicians and requires no power-down or lockout procedure for use. Store in the included plastic case when not in use to protect the carbide blade from impact or contamination. Allow the micrometer and workpiece to reach thermal equilibrium before measuring, particularly in environments with temperature variation, to minimize thermal expansion error. Calibration should be verified against a known standard before use and maintained per your facility quality plan.
