Internal dial bore gauge M208.425 — analogue indicator, 160–250 mm range, 0.01 mm resolution (Metav IndustryLine)

An Internal dial bore gauge M208.425 designed for precise internal diameter measurement in workshop and inspection environments, suitable for standard machine‑shop tasks and quality control routines.

*160–250 mm measuring range for internal diameters
*500 mm measuring depth for deep bores
*Dial gauge resolution 0.01 mm for fine readings
*Repeatability 0.02 mm ensures consistent results

Precision that supports production decisions

The instrument delivers repeatable measurements thanks to a 0.01 mm dial resolution combined with a verified repeatability of 0.02 mm, which makes it suitable for routine dimensional control and process checks on turned and bored parts. The analogue indicator gives an immediate, continuous reading that is easy to interpret during set‑up and in‑process inspection. This level of precision supports rational decision making by reducing rework and ensuring parts conform to specified tolerances.

Reach and geometry for demanding internal measurement

With a measuring range of 160–250 mm and a measuring depth of 500 mm, this bore gauge is engineered for components that require access well beyond the face, such as deep housings and sleeves. The gauge features five measuring pins (Ø8) that provide stable contact and minimise tilt, improving the reliability of readings in off‑centre bores. The matt‑chrome device holder offers a corrosion‑resistant mounting point that keeps the probe geometry steady during measurement.

Robust design for workshop use and transport

Weighing approximately 1.4 kg, the instrument balances rigidity and portability for single‑operator use. The analogue construction reduces dependency on batteries and electronic components, favouring long service life in demanding shop environments. Delivery includes a dedicated transport case for safe handling and secure storage during transfer, preserving calibration and protecting the measuring faces between uses.

Practical classification and typical applications

Classified in the standard range for internal measuring equipment (covering 100–300 mm), this gauge is intended for general mechanical and metalwork applications where a compromise of reach, stiffness and ease of handling is needed. Typical uses include inspection of bores on housings, set‑up checks on machining centres and first‑piece verification during production runs. The combination of depth and range makes it a flexible option for jigs, fixtures and medium‑sized components.
