Digital three‑point internal micrometer M312.262.S — Metav IndustryLine, 250–275 mm, carbide measuring faces

The Digital three‑point internal micrometer M312.262.S is a precision instrument engineered for reliable blind‑hole measurement in medium‑to‑large components.

• High-resolution 0.001 mm readout
• Carbide measuring faces for wear resistance
• Blind‑hole range 250–275 mm
• RB 4 data interface for digital output

Precise, repeatable measurements for critical bores

The three‑point contact design centralises the measuring force and yields a stable datum even in deep blind holes, making it suitable for repeatable quality checks. With a measuring range of 250–275 mm, a measuring depth of 140 mm and a display resolution of 0.001 mm, the instrument offers a fine balance of reach and precision. The stated accuracy of ±0.009 mm supports use where traceable, repeatable bore dimensions are required, reducing rework and inspection time.

Faster inspection through digital integration

Equipped with a digital display that includes ON/0, mm/inch, ABS, PRESET and HOLD functions, the gauge reduces transcription errors and accelerates data capture. The RB 4 data output allows direct connection to statistical process control or data logging systems, streamlining inspection workflows and saving operator time during batch checks. This combination of clear readout and connectivity supports efficient, documented quality assurance.

Built for sustained workshop use

Carbide measuring faces provide excellent wear resistance where repeated contact is inevitable, maintaining consistent results over long service intervals. The instrument’s robust construction and manageable mass ensure stable handling during measurement. Delivery excludes a setting ring, so calibration or a reference standard should be prepared if required for traceable setup. The unit is supplied ready for transport in a protective case to prevent damage in transit.

Practical classification and typical applications

With a maximum range of 275 mm this gauge falls into the standard measuring class (100–300 mm), offering the ideal compromise between reach, stiffness and one‑hand usability for general engineering and toolroom use. Typical applications include verification of blind bores in housings, bearing seats and large fixtures where accurate internal diameter control is essential. The three‑point mechanism simplifies centring in irregular bores and provides a reliable result where conventional callipers struggle.

FAQ

What measurement range does this instrument cover?
The Digital three‑point internal micrometer M312.262.S covers a measuring range of 250–275 mm, suitable for medium‑sized bores.

Is the gauge suitable for blind‑hole measurement?
Yes. The device is specifically configured for blind‑hole (sackloch) measurement and features a three‑point contact system optimised for such applications.

What resolution and accuracy can be expected?
The instrument provides a resolution of 0.001 mm and an accuracy of ±0.009 mm, enabling detailed, repeatable measurements.

What material are the measuring faces made from?
The measuring faces are made of carbide (HM), chosen for wear resistance and long service life under frequent use.

Is a setting ring included for calibration?
No, the delivery is without a setting ring; a suitable reference standard should be used for calibration and verification.
