12.7mm Digital Dial Indicator 0.01mm Resolution Absolute 330° Rotating Display, IP54 - Metav IndustryLine

Taking advantage of the combination of an absolute measuring system, 0.01 mm resolution and a 330° rotatable display delivers reliable, repeatable readings on the shop floor. Fast integration into inspection routines is enabled via the RB 6 data interface; order the instrument directly through Metav Werkzeuge or consult our specialists for application advice.

M301.031 Digital Indicator — 12.7 mm range, 0.01 mm resolution (Metav IndustryLine)

The M301.031 is a compact digital indicator designed for precision inspection and tool‑setting tasks with an absolute measuring system and a rotatable display for flexible reading in confined workspaces.

• Absolute measuring system, 0.01 mm resolution
• Display rotatable through 330° for flexible reading
• IP54 protection for workshop environments
• Repeatability 0.005 mm, measuring force >1.5 N

Reliability and repeatable precision for inspection tasks

The instrument combines an absolute measuring system with 0.01 mm resolution and a documented repeatability of 0.005 mm, providing measurement stability for serial inspection and set‑up tasks. The scale runs on a glass guide, which improves scanning accuracy and reduces play compared with plain plastic guides; the result is consistent numeric output even under repeated contact. The relatively firm measuring force >1.5 N prevents ambiguous needle bounce and helps maintain contact with the measured surface, which translates into fewer reworks and clearer pass/fail decisions.

Workshop‑tough design with ergonomic reading

Built for day‑to‑day workshop use, the gauge offers IP54 protection against dust and splash water and a 330° rotatable display that keeps results legible from awkward angles. At a compact measuring range of 0–12.7 mm and a weight of 0.29 kg, the unit is easy to manoeuvre without compromising stiffness. The visible, well‑laid-out display and robust construction reduce operator fatigue and speed up repetitive measurements, making the device suitable for both bench inspection and machine‑side checks.

Integrated digital control for process traceability

The electronic readout supplies a broad set of functions — ON/OFF, ORIGIN, 0/ABS, PRESET, TOL, mm/inch and +/- keys — to adapt quickly to different measurement routines. An RB 6 data output enables direct transfer of measured values into SPC systems or portable data loggers, supporting automated documentation and trend analysis. The absolute system runs on a 3 V supply, keeping the zero reference even after power cycles and simplifying workflow by eliminating repeated re‑referencing during shift changes.
