Three-point internal micrometer — self‑centring, 225–250 mm (Metav IndustryLine)

The Three-point internal micrometer is a self‑centring instrument designed for precise internal diameter measurement in production, inspection and tooling environments.

• Self‑centring three‑point design for bore alignment
• Measuring range 225–250 mm
• Accuracy 0.012 mm
• Hardened measuring faces for wear resistance

Precision that improves process control

The instrument delivers an accuracy of 0.012 mm, a level suited to routine quality checks and dimensional inspections where repeatability matters. Its resolution (reading) of 0.005 mm ensures small deviations are visible on the scale, reducing the risk of out‑of‑tolerance parts progressing down the line. As an analog device with a mechanical readout, it performs reliably in environments where electronics might be affected by coolant, chips or electromagnetic interference. The clear reading and consistent mechanical behaviour make it a practical choice for both shop‑floor metrology and incoming inspection.

Faster, more reliable bore measurement through self‑centring action

The self‑centring three‑point concept centralises the measuring heads automatically inside the bore, which reduces alignment errors and shortens the measurement routine. Compared with single‑point gauges, the three‑point geometry averages out local form deviations and provides a stable centre reference, simplifying both first‑article checks and batch sampling. This design is particularly effective on cylindrical bores, bushes and stepped bores where reliable central contact and repeatable seating are required to achieve meaningful comparisons between parts and drawings.

Robust design for regular workshop use

Built for continuous use, the instrument features hardened measuring faces that withstand abrasion from repeated contact and help maintain calibration over time. The mechanical construction avoids dependence on batteries, which improves availability in busy inspection rooms. Ergonomic ratchet or thimble control (typical for this class of micrometer) allows consistent measuring force, helping to keep human‑introduced variability low. The tool is identified as M836.724, making it straightforward to reference in inspection procedures and tool inventories.
