Mitutoyo 323-350-30 Electronic Disc Micrometer 0-1 in IP65

Product Description

The MITUTOYO 323-350-30 is an electronic disc micrometer designed for precision measurement of grooves, keyways, and other recessed or hard-to-reach features. It covers a measurement range of 0 to 1 inch with a resolution of 0.00005 inch and an accuracy of 0.0002 inch. The 20mm disc anvil with a 0.40mm edge thickness allows the tool to seat cleanly in narrow slots where a standard flat anvil cannot reach. The ratchet stop thimble delivers consistent measuring force on every reading. A licensed technician or precision machinist installs and uses this instrument on the shop floor or in the field.

The 323-350-30 is suited for dimensional inspection in manufacturing, maintenance, and quality-control applications where conventional micrometer anvils cannot access the target surface. The IP65 water resistance rating protects the instrument against dust ingress and low-pressure water jets, making it appropriate for use in wet or coolant-exposed shop environments. Data output capability allows readings to be sent directly to a statistical process control or data-logging system, reducing transcription error during inspection routines.

Key Features

• 0.00005 inch resolution with 0.0002 inch accuracy for high-precision groove and keyway measurement
• 20mm disc anvil with 0.40mm edge thickness accesses narrow slots and recessed features

• Ratchet stop thimble ensures repeatable, consistent measuring force
• Data output port supports direct connection to SPC or data-logging equipment
• TUV Certified; includes SR44 battery and plastic storage case

Compatibility

Designed as an OEM-style precision measurement instrument for use in general dimensional inspection of grooves, keyways, and disc-type workpiece features within a 0 to 1 inch range.

Installation Notes

This instrument is used and maintained by machinists, metrologists, or precision inspection technicians. Before use, confirm the anvil and spindle faces are clean and free of debris to avoid measurement error. Calibrate or verify the zero setting against a known reference standard according to your facility quality procedures. Avoid impact, dropping, or exposing the instrument to temperatures or environments beyond manufacturer-specified limits.
