Three‑point internal micrometer M312.259.S — digital, 175–200 mm (Metav IndustryLine)

The Three‑point internal micrometer M312.259.S is a digital measuring instrument designed for accurate inspection of blind holes and large bores in workshop and production environments.

• Digital readout with ABS and mm/inch
• Three‑point head for blind‑hole measurement
• Measuring range 175–200 mm, 140 mm depth
• Carbide measuring faces and robust build

High‑precision digital measurement for process reliability

The instrument provides a digital display with a resolution of 0.001 mm and a measured accuracy of ±0.007 mm, delivering reproducible values that support statistical process control and reduce scrap rates. The readout includes ON/0, mm/inch, ABS, PRESET and HOLD functions, enabling straightforward switching between measurement modes and stable capture of values. Integrated RB4 data output facilitates wired transfer to data loggers or SPC systems, streamlining documentation and traceability in inspection workflows.

Purpose‑built geometry for blind‑hole inspection and extended reach

Equipped with a three‑point head, the instrument is optimised for centring inside blind bores where conventional two‑point devices are less reliable; the design allows consistent contact with the bore even when the measurement cannot pass fully through. The effective measuring range of 175–200 mm with a 140 mm measuring depth positions this device in the standard class for workshop metrology, offering a balance of reach and stiffness suited to machine and toolroom applications. Delivery excludes a setting ring, so calibration or reference standards should be arranged if required.

Durable construction and workshop usability

Constructed with carbide measuring faces, the device resists wear and maintains measurement integrity under frequent use. At around 3.1 kg, the instrument remains manageable for bench or fixture work while its solid build reduces deflection during measurement. A protective transport case is supplied for safe handling and storage during transit. Clear mechanical design and intuitive buttons make the instrument readily adoptable by inspection technicians, while the combination of robust components and digital connectivity supports long‑term reliability on the shop floor.

FAQ

What types of measurements can this instrument perform?
The M312.259.S three‑point internal micrometer performs internal diameter measurements of blind bores and large bores, providing reliable centring and repeatable readings for inside measurements.

What accuracy and resolution does the instrument offer?
The instrument offers a resolution of 0.001 mm and an accuracy of ±0.007 mm, making it suitable for precise workshop inspection and quality control tasks.

Is a setting ring included for calibration?
Delivery is made without a setting ring; a reference standard or calibration ring should be used separately to verify zero and traceability during initial setup.

How are readings transferred to a PC or data logger?
Readings can be exported via the RB4 data output, allowing wired connection to data acquisition systems or SPC software for documentation and analysis.

Are the measuring faces suitable for high‑use environments?
Yes; the instrument is fitted with carbide measuring faces for enhanced wear resistance and longevity in frequent inspection cycles.
