Uni. Micrometer M309.084 — Universal micrometer 100–125 mm with friction ratchet (Metav IndustryLine)

The Uni. Micrometer M309.084 is a universal workshop micrometer designed for precise external measurements in the standard range, offering interchangeable measuring inserts and a friction ratchet for reproducible contact pressure

• Universal range 100–125 mm
• Friction ratchet for consistent pressure
• Non-rotating measuring spindle
• Includes 7 pairs of special measuring inserts

Tight tolerances for dependable quality control

The micrometer delivers a measuring range of 100–125 mm with a reading resolution of 0.01 mm and a stated accuracy of ±0.012 mm, making it well suited to routine quality control in metalworking and component inspection. The calibrated Vernier-style scale and fine spindle control ensure measurements remain repeatable; the friction ratchet prevents over-tightening and stabilises contact force, which reduces operator-induced variation. This focus on measurable performance supports faster decisions on production tolerances and rework.

Durable build for everyday workshop use

Engineered for shop-floor robustness, the instrument combines a painted frame with a matt-chrome measuring drum, providing corrosion resistance and an easy-to-read surface. The spindle is designed as a non-rotating measuring spindle, minimising wear on the contact surfaces and improving longevity. At approximately 1 kg, the tool balances solidity with manageable handling, and the factory standard construction (Werksnorm) emphasises consistent manufacturing quality across batches.

Flexible measurement capability with interchangeable inserts

Supplied with seven pairs of special measuring inserts, the micrometer adapts to a variety of external geometries without the need for separate micrometers. The interchangeable anvils permit secure contact on small radii, flats or stepped surfaces, expanding the micrometer’s practical use in fixture, mould and general component measurement. Each insert set is engineered to mate precisely with the measuring face, preserving the instrument’s stated accuracy and making set-up quicker in mixed-production environments.

Ready-to-use delivery and workshop integration

The micrometer is delivered in a transport case suitable for workshop handling, protecting the instrument and its inserts during storage and transit. The scope of delivery includes the instrument and the seven pairs of inserts, allowing immediate deployment on the shop floor. Clear, measurable data and robust mechanics mean the device integrates smoothly into existing inspection routines, supporting traceable measurement results and reducing downtime for calibration checks.
