Digital Three‑Point Internal Micrometer M312.260.S — Digital instrument, 200–225 mm range, carbide measuring faces (Metav IndustryLine)

The Digital Three‑Point Internal Micrometer M312.260.S is a workshop‑grade instrument designed for precise blind‑hole measurement in production and quality control.

• Digital readout with ON, mm/inch, ABS, PRESET, HOLD
• Measuring range 200–225 mm for blind‑hole inspection
• Carbide measuring faces for wear resistance
• RB‑4 data output for integration into systems

Precise measurement where repeatability matters

The instrument delivers repeatable internal measurements across its measuring range 200–225 mm, classifying it in the Standard category for general machine‑shop and metalworking tasks. The digital readout offers a fine resolution of 0.001 mm, while the stated accuracy ±0.008 mm (8 µm) ensures results that meet routine production tolerances. This combination reduces measurement uncertainty and supports consistent quality control procedures without slowing cycle times.

Fast data capture and process integration

Equipped with an intuitive display and multiple function keys (ON/0, mm/inch, ABS, PRESET and HOLD), the instrument streamlines workflow for inspection tasks. The RB‑4 data output enables direct transfer of measured values into SPC or data‑collection systems, cutting manual transcription errors and accelerating documentation. For manufacturers seeking measurable productivity gains, the ability to log results electronically represents a clear operational advantage.

Robust mechanical design for blind‑hole work

The three‑point measuring principle provides stable contact and self‑centring inside bores, which is particularly beneficial for blind‑hole measurement where flank accessibility is limited. The contact surfaces are carbide measuring faces, delivering high wear resistance and long service life in production environments. With a measuring depth of 140 mm and a solid build weighing 4.8 kg, the device combines stiffness with the reach required for medium‑sized components, reducing rechecks and maintenance intervals.

Practical workshop readiness and setup

Delivery excludes a setting ring, so initial reference calibration requires a suitable master gauge (refer to internal standards). The model is indicated as the 2023 version and is configured for direct workshop use, providing clear on‑screen functions for unit changes and presetting. The compact control layout simplifies operation for operators with varying experience levels and supports quick familiarisation during shift handovers.

FAQ

Which bore types is this instrument intended for?
The instrument is designed specifically for blind‑hole measurement and performs well on medium‑sized internal bores within the 200–225 mm range.

What level of accuracy can be expected in routine inspection work?
Routine inspections with this digital internal micrometer typically achieve an accuracy of ±0.008 mm, with a display resolution of 0.001 mm for clear readouts.

Is a setting ring included for calibration?
No; delivery is without a setting ring. A calibrated master gauge or ring standard is recommended for initial setup and verification.

How are measurement results transferred to quality systems?
Measurement values can be exported via the RB‑4 data output, enabling direct integration with SPC and data‑collection systems to avoid manual entry errors.

Are the measuring faces suitable for high‑volume production?
Yes; the carbide measuring faces provide enhanced wear resistance and extended service life under industrial use.
