Mitutoyo 395-363-30 Electronic Tube Micrometer 0-1 in

Product Description

The MITUTOYO 395-363-30 is an electronic tube micrometer designed for precise outside-diameter measurement of cylindrical and tubular workpieces. It features a spherical carbide anvil and a carbide spindle that make controlled contact with curved or thin-walled surfaces where a flat anvil would give inaccurate readings. The ratchet stop thimble delivers consistent measuring force on every use, reducing operator-to-operator variation. Accuracy is rated at 0.00015 inches, making it suitable for quality-control work where tight tolerances must be verified. The satin chrome finish reduces glare in shop lighting. Licensed HVAC, plumbing, and mechanical trades rely on this instrument when checking tubing stock and fittings against specification.

This micrometer covers a measurement range of 0 to 1 inch and is suited for inspecting small-diameter tubes, thin-wall pipe sections, and precision cylindrical components in both shop and field environments. The electronic readout simplifies direct readings without interpolation, reducing misread errors during high-volume inspection tasks. The non-rotating spindle design protects delicate tube surfaces from scoring during measurement. It ships with one battery, a storage box, a wrench key, and a setting standard for units measuring from 25 mm upward.

Key Features

• Spherical carbide anvil conforms to curved tube surfaces for accurate wall and diameter readings
• Carbide spindle resists wear during repeated contact with hardened or abrasive workpiece materials
• Ratchet stop thimble applies consistent measuring force regardless of operator technique
• Non-rotating spindle prevents surface marring on thin-wall tubing
• Electronic digital readout rated to 0.00015 inch accuracy
• Satin chrome finish minimizes glare and corrosion in shop environments
• TUV certified to recognized metrology standards

Compatibility

Designed as an OEM-style precision measurement tool for outside-diameter inspection of cylindrical and tubular workpieces within a 0 to 1 inch range. No specific equipment or system compatibility was stated in the product data.

Installation Notes

Calibration and use should be performed by a qualified metrologist or trained technician familiar with micrometer procedure. Before measuring, clean both the anvil and spindle faces and zero the instrument against the included setting standard. Store the micrometer in its case with the spindle slightly open to prevent spring set. Do not overtighten the thimble beyond the ratchet mechanism, as excess force will compromise accuracy.
