M309.071 Depth Micrometer — Flat measuring faces, 0–200 mm range, 0.01 mm graduation (Metav IndustryLine)

The M309.071 Depth Micrometer is a precision analogue depth gauge designed for standard workshop and inspection tasks, offering a modular measuring system with exchangeable rods and a sturdy transport case.

• 0–200 mm measuring range for standard tasks
• 0.01 mm graduation for fine depth readings
• Ratchet stop for reproducible measuring force
• Exchangeable measuring rods, 8 pieces included

Precise and repeatable depth measurement for production control

The micrometer delivers a 0–200 mm measuring span with a fine 0.01 mm graduation and a manufacturer-stated measurement accuracy of ±0.006 mm, making it well suited to routine quality checks and process control in metalworking environments. The analogue spindle and ratchet stop provide a consistent contact force, which reduces operator-induced variation and ensures each measurement is comparable. For users accustomed to digital readouts, the mechanical scale still offers clear, reliable readings while remaining robust against workshop conditions. The built-in bridge provides a stable reference for depth probes, and the flat measuring faces are particularly useful where full-area contact is required for repeatable positioning.

Flexible system design that adapts to different components

A key practical advantage is the set of exchangeable measuring rods supplied with the instrument — eight rods are included to cover a wide variety of groove depths, bores and stepped components. The modular approach reduces the need for multiple dedicated gauges: rods can be changed quickly to suit different tasks, which shortens set-up times and keeps production moving. The instrument’s bridge dimension of 100 × 16 mm gives a compact, rigid support that balances accessibility and stiffness; this makes the tool suitable for typical machine‑shop parts where a standard-length depth gauge is the most efficient choice.

Workshop-ready robustness and handling for everyday use

Built for everyday handling, the depth micrometer is delivered in a protective transport case that safeguards the measuring elements during storage and transit. The ratchet stop prevents over-tightening and contributes to consistent measuring force, while the analogue mechanism requires no batteries and is simple to maintain. Flat measuring faces simplify alignment at the measurement site and are less likely to snag on workpiece edges. Classified within the standard measuring range category, this instrument offers the best compromise between reach, rigidity and single‑hand operation — ideal for machine shops, maintenance teams and in-line inspection stations.
