Digital dial gauge M301.052.4 — 25 mm bridge, digital readout (Metav IndustryLine)

The Digital dial gauge M301.052.4 is a compact inspection instrument designed for bench and shop‑floor measurement tasks where clear digital readout and extended reach are required

• Compact 25 mm measuring bridge
• High resolution 0.01 mm display
• mm/inch selectable digital readout
• Extensions 10–100 mm for deeper reach

Consistent precision for routine inspection

The instrument delivers a clear 0.01 mm resolution on a digital display with an inch equivalent of 0.0005 in, providing repeatable numeric readings for dimensional checks and process documentation. With a concise 0–25 mm measuring range and a digital ABS/PRESET function, the unit reduces interpretation errors compared with analogue indicators and supports faster go/no‑go decisions during incoming inspection or in‑process control. The robust numeric output is suitable for logging and simple quality control where consistent stepwise comparison is required.

Modular bridge extensions for concealed or deep features

A fixed 25 mm bridge and a generous 140 mm measuring depth combine with exchangeable extensions (10, 20, 40, 70 and 100 mm) to reach recessed bores, stepped surfaces and inner shoulders without improvised fixtures. The modular extension concept keeps the measuring axis aligned while extending reach, which reduces setup time and preserves measurement stability. This approach enables reliable checks of recess depths and internal shoulders without sacrificing the precision expected from a short‑span dial system.

Digital controls that reduce cycle time

The readout features dedicated 0/ON, ABS/PRESET and mm/inch buttons for immediate switching between absolute and preset modes and instant changeover between metric and imperial units. The option to invert the measuring direction streamlines measurements taken from different orientations and reduces repositioning of workpieces. These control conveniences translate into fewer handling steps and faster inspection cycles, particularly when alternating between batch sizes or when operators must log readings in different unit systems.

Built for everyday workshop use

Finished to a practical workshop standard (Werksnorm) and weighing approximately 0.62 kg, the gauge balances rigidity with portability for bench work and mobile inspection tasks. The Ø25 mm bridge provides a stable interface that resists bending under normal use, and the digital display reduces subjective reading errors. Designed as a straightforward measuring tool for routine dimensional verification, this instrument fits into inspection benches where clear numeric data and physical reach are required without complex setup.

FAQ

How accurate is the instrument for routine checks?
The device provides a resolution of 0.01 mm (0.0005 in) and a stable digital reading via ABS/PRESET, making the Digital dial gauge M301.052.4 suitable for standard workshop and incoming‑inspection tasks where metric sub‑hundredths are required.

Can the gauge reach recessed features and bores?
Yes. The gauge offers a measuring depth of 140 mm from the bridge and is supplied with modular extensions of 10, 20, 40, 70 and 100 mm to access deep or stepped geometries.

Is it possible to switch between metric and imperial units?
The digital readout includes an mm/inch function so measurements can be toggled quickly between metric and imperial units on the M301.052.4.

Are readings reversible for different orientations?
Measuring direction reversal is possible, which simplifies measurements taken from opposite orientations and avoids additional re‑fixturing.

What delivery standard does the product follow?
The instrument is supplied to Werksnorm (factory standard) as indicated in the product data and is intended for immediate use in standard inspection workflows.
