MITUTOYO SERIES 395, 115, 295 TUBE MICROMETER SPHERICAL ANVIL AND SPINDLE TYPE BOTH SIDE BALL

Product Overview

The Mitutoyo Series 395, 115, and 295 Tube Micrometers feature spherical anvils and spindles designed specifically to measure workpieces with concave-concave surfaces. The spherical design ensures contact with the workpiece at a single point, increasing measurement accuracy. Series 395 models provide IP65 water/dust protection, while all models are equipped with a Ratchet Stop to ensure a constant measuring force.

Key Features & Capabilities

Spherical Anvil and Spindle: Makes point-contact with concave-concave surfaces to maximize measurement precision.
IP65 Water/Dust Protection: Built-in dust and water protection standard on Series 395 Digimatic models.
Ratchet Stop: Delivers repeatable, constant measuring force across operations.
Position Detection: Electromagnetic rotary sensor utilized on Digimatic models (Series 395).
Battery Life: Approximately 2.4 years under normal use (Series 395).
