Mitutoyo 395-352-30 Spherical Face Micrometer IP65

Product Description

The MITUTOYO 395-352-30 is an electronic spherical face micrometer designed for precise outside measurement of curved and contoured surfaces. It covers a measurement range of 1 to 50.8mm with a resolution of 0.0001 inch and accuracy up to 0.0001 inch. The spherical anvil face allows contact on convex and concave workpiece surfaces where a flat anvil would rock or slip. A ratchet stop thimble delivers consistent measuring force, and the digital readout with data output port allows direct transfer of measurement values to SPC systems or data loggers. Licensed metrologists, quality technicians, and precision machinists are the primary users.

This micrometer suits inspection and production environments where curved-surface measurement is required, including tube wall thickness, ball bearing dimensions, and radius checks on machined components. The IP65-rated housing resists coolant splash and fine dust ingress, making it suitable for shop-floor use. Electronic operation provides fast, clear readout without manual interpolation of thimble graduations. The satin chrome finish reduces glare under shop lighting. The unit is TUV certified and ships with one SR44 battery installed.

Key Features

Compatibility

Designed as a direct-use electronic spherical face micrometer for precision measurement applications requiring contact on non-flat surfaces within a 1 to 50.8mm range.

Installation Notes

This instrument requires no installation but should be calibrated and zeroed before use per standard metrology practice. Handle with clean, dry hands or cotton gloves to prevent thermal expansion from body heat affecting readings. Store in the supplied case away from strong magnetic fields and temperature extremes. Battery replacement uses a standard SR44 cell; follow the instrument manual for replacement procedure to maintain calibration integrity.
