Digital three‑point internal gauge M312.261.S — 225–250 mm, carbide measuring faces

A Digital three‑point internal gauge M312.261.S designed for precise measurement of blind bores and large internal diameters in production and quality control environments.

• Digital readout with mm/inch & ABS
• Carbide measuring faces for long life
• Measuring depth 140 mm for blind bores
• Delivered in protective case

Exceptional repeatability for blind‑bore measurement

The instrument provides three‑point contact that centres automatically in the bore, giving consistent readings across the full 225–250 mm range. With a stated accuracy of ±0.008 mm and a fine resolution of 0.001 mm, the gauge supports tight tolerance inspection in machining and assembly processes. The carbide measuring faces offer wear resistance and long service life, which reduces drift and the need for frequent recalibration, increasing uptime in production runs.

Practical digital features to speed up inspection workflows

Equipped with a clear digital display supporting ON/0, mm/inch, ABS, PRESET and HOLD, the unit simplifies measurement routines and reduces transcription errors. The built‑in data output RB 4 enables direct transfer of results to data loggers or quality software, making statistical process control and traceable documentation straightforward. These capabilities translate into faster inspection cycles and improved process control in a shopfloor setting.

Robust construction and ready‑to‑use delivery

The gauge is built for industrial use: the carbide measuring faces withstand abrasive conditions, while the instrument’s overall design supports stable handling at the stated measuring depth of 140 mm. Delivered in a protective case for secure transport, the package does not include a setting ring. The unit’s mass (approx. 4.8 kg) reflects solid build quality and helps maintain measurement stability when working with larger bores.

Where this gauge adds value in production and quality assurance

Engineered for blind‑bore inspection in housings, pump casings and similar components, the device is ideal for shops that require repeatable internal measurements across medium‑sized diameters. Classified within the Standard measuring class (up to 300 mm), it offers a practical balance of reach and stiffness, making it suitable for routine machine‑shop quality control as well as final inspection stations. Metav’s distribution ensures a reliable supply chain and expert advice for integration into existing measurement routines.
