M209.033 Internal Quick‑Action Dial Gauge – 20–40 mm, 0.01 mm resolution (Metav IndustryLine)

The M209.033 Internal Quick‑Action Dial Gauge is a compact analogue instrument designed for rapid inspection of internal features such as bores and grooves in workshop and inspection environments.

• Internal quick-action measurement 20–40 mm
• Fine resolution 0.01 mm for precise checks
• Accuracy ±0.03 mm for consistent results
• Rounded contact tips R0.5 for sensitive surfaces

Faster internal checks to speed up inspection workflows

For routine verification of bores, slots and grooves the instrument delivers swift contact and immediate visual feedback. The analogue dial gauge layout with a quick‑action contact allows operators to complete repetitive internal measurements faster than with separate probe setups, reducing cycle time on the shop floor. The compact measurement span of 20–40 mm matches common small‑bore tasks in production and maintenance, enabling quick sorting between acceptable and out‑of‑tolerance parts without complex fixturing.

Precision that supports reliable decisions

With a reading step of 0.01 mm and declared accuracy of ±0.03 mm, this device provides a balance between fine resolution and industrial robustness. The mechanical construction minimises backlash and supplies repeatable indications suitable for in‑process checks and first‑off inspection. Where microscopic deviations matter, the clear analogue scale helps technicians see trends at a glance and decide on corrective action, while the instrument’s specification ensures results that are compatible with typical workshop tolerances.

Gentle contact for delicate interior finishes

The measuring contacts are shaped as rounded contact tips (R0.5) to prevent marking or damaging sensitive surfaces inside bores and grooves. This tip geometry supports measurement of finished components and soft materials while maintaining stable contact. The gentle interface is particularly useful when checking components with plated or polished bores, preserving surface integrity during inspection and helping to avoid rework caused by measurement damage.

Built for everyday workshop handling

Engineered as an analogue, quick‑action tool, this internal gauge is straightforward to use and robust in daily operation. The construction favours frequent handling and easy resetting between measurements, while the clear dial face gives unambiguous readings for fast decision‑making at the bench. Its design supports standard inspection routines and complements other dial indicators and gauges in a metrology kit, making it a practical choice for production, maintenance and quality departments.
