The Insize 3108 IP65 digital outside micrometer delivers precise, repeatable measurements in challenging environments. With IP65 dust/waterproof protection and a 0.001 mm resolution, it’s built for reliability around machine fluids and coolants.

• IP65 waterproof/dustproof: Enclosed to resist dust and water jets, maintaining accuracy in dirty or damp shop conditions.
• Measurement range: 0–25 mm (0–1") external measurements for small parts and components.
• Resolution: 0.001 mm (0.0001") display for fine, close-tolerance readings.
• Carbide measuring faces: Durable, wear-resistant contact surfaces designed for long life in demanding environments.
• ABS/INC: Switch between Absolute and Incremental measurement modes for flexible setup and quick zeroing.
• Digital display: Clear LCD readout with straightforward on/off, set, and mm/in button functionality for fast readings.
• Spherical anvil included: Versatile contact geometry to accommodate a range of part contours and increases measurement consistency.
• Ratchet mechanism: Built-in ratchet ensures consistent pressure for repeatable measurements every time.
• Power and battery: Uses a standard SR44 or LR44 battery for easy replacement in the field.
• Setting standards included: Calibration standards are provided for quick verification (excluding the 0–25 mm range).

Designed for engineers, machinists, and maintenance technicians, the 3108 digital outside micrometer helps you achieve fast, dependable measurements in environments exposed to coolant, oil, and dust. Its carbide faces, precise 0.001 mm resolution, and IP65 protection reduce downtime and rework, while the ABS/INC modes and included standards support accurate calibration and traceability in daily workflows.
