INSIZE 3127-E16 Digital Three Points Internal Micrometer, 1.2-1.6"/30-40mm

INSIZE 3127-E16 Digital Three Points Internal Micrometer

Are you looking for a precision digital internal micrometer with a self-centering three-point contact design, built to deliver accurate and repeatable measurements of internal diameters between 1.2″ and 1.6″ (30–40 mm)? The INSIZE 3127-E16 is designed for industrial and metrology applications, it combines a rugged IP-rated body with a high-resolution digital interface, data output capabilities, and long battery life to support modern quality control workflows.

Key Features

• Wide Three-Point Contact — Uses three carbide measuring faces for stable, self-centering measurements, minimizing user error and improving repeatability.
• High-Resolution Readout — Displays measurements at 0.00005″ / 0.001 mm, enabling very fine resolution.
• Rugged & Resistant Design — Rated IP54 for dust and splash resistance, making it suitable for shop-floor use.
• User-Friendly Controls — Features buttons for On/Off, Set, Inch/mm toggle, and ABS/INC mode for flexible operation.
• Data Output — Equipped with a data output function (e.g., RS-232) for integrating measurements into SPC systems or external logging.
• Battery and Power Management — Operates on an LR44 battery, with automatic power-off to conserve energy.
• Ratchet Stop Mechanism — Ensures constant contact force for reliable measurement consistency.
• Precision Construction — Carbide measuring faces for wear resistance and long-term durability.
• Optional Connectivity — Supports optional data-output cable for easier integration with data collection systems.
