M304.235 outside micrometer (175–200 mm) — friction ratchet, matt chrome-plated thimble

The M304.235 outside micrometer is a precision workshop instrument for reliable external measurements across a 175–200 mm range, engineered for repeatable contact and easy handling in production and inspection environments.

• 175–200 mm measuring range
• 0.01 mm graduation for precise readings
• Friction ratchet for reproducible contact
• Matt chrome-plated measuring thimble

Repeatable contact for consistent results

The mechanical design focuses on measurement reproducibility: a friction ratchet determines the measuring force and prevents over-tightening, making every reading more consistent across repeated cycles. Combined with the fine 0.01 mm graduation, this behaviour reduces operator-induced variation and supports quality-control processes where traceable, repeatable external measurements are required. The construction aligns with industrial expectations, helping to shorten inspection times without compromising accuracy.

Fast adjustment and clear reading mechanics

A spindle pitch of 0.5 mm gives predictable axial movement per thimble rotation, which accelerates setup while preserving fine adjustment capability. The matt chrome-plated thimble improves legibility under workshop lighting and reduces surface reflections that can hinder quick readings. Built as a mechanical instrument to DIN 863, the micrometer uses established metrology principles so operators familiar with conventional micrometers will find the scale and tactile feedback immediately intuitive.

Robust transport and workshop readiness

Designed for everyday use in production settings, the instrument is supplied in a protective case for secure transport and storage. The solid construction of the frame and the finished thimble make it suitable for regular handling on the shop floor while the supplied case reduces the risk of accidental damage during transit. Metav’s role as a precision partner ensures dependable availability from the Emmerich hub, supporting customers who require consistent supply and clear product information for procurement and process planning.
