Quernuten internal gauge M311.012 — analogue 0.01 mm double‑scale for T‑slot measurement (Metav IndustryLine)

Quernuten internal gauge M311.012 is an analogue measuring instrument designed for accurate inspection of internal T‑slots and similar narrow features in fine mechanical parts

• Analogue reading with 0.01 mm resolution
• Double scale for internal and external measurement
• Measuring range inside 1.6–26.5 mm

Compact precision for small features and fine mechanical work

This measuring tool belongs to the micro class of instruments, optimised for short‑reach measurements where rigidity and repeatability matter. With a 0.01 mm reading step and an analogue nonius, the device delivers a level of detail that supports tight tolerance checks on miniature components. The compact geometry and controlled instrument length reduce flexing during measurement, resulting in consistent inside‑slot readings across multiple parts and reduced rework in assembly operations.

Clear dual scales reduce measurement steps and uncertainty

The integrated double scale provides both internal and external references on the same instrument, eliminating the need for multiple tools when switching between checks. For production environments where throughput and traceability are important, this consolidation shortens inspection cycles and lowers handling time. The robust measuring mandrel with a Ø 13 mm contact ensures reliable seating in T‑slots, while the precise spindle pitch enables fine adjustment without overshoot.

Designed for workshop durability and safe transport

Delivery includes a protective case suitable for safe transport and storage of the gauge. The solid construction and analogue mechanism are chosen for longevity under regular workshop use, offering dependable service in machine shops and toolrooms. The non‑electronic design removes dependence on batteries or electronic interfaces, simplifying maintenance and documentation for quality systems that prefer mechanical measuring artefacts.
