Dial indicator M2 / 30T — 30 mm range, 0.01 mm resolution (Käfer)

Dial indicator M2 / 30T for comparative measurements, runout checks and workshop inspection tasks in production and maintenance environments

• Large 30 mm measuring span
• Fine 0.01 mm graduation
• 58 mm outer bezel for easy reading
• 1.0 mm pointer revolution per rotation

High-precision readings that keep processes stable

The dial indicator M2 / 30T delivers consistent, traceable readings thanks to its 0.01 mm graduation and a 30 mm measuring span. The instrument is designed for comparative measurement tasks such as runout checks and parallelism testing; the scale is easy to read through the 58 mm bezel, and the 1.0 mm per revolution pointer ratio simplifies interpretation of multi-revolution measurements. This mechanical gauge is suited to applications where repeatability and rapid visual assessment are required, and the specification supports decision-making in production control.

Robust workshop performance and straightforward handling

Built for routine use, the indicator combines a clear dial with a durable mechanical movement to withstand frequent handling in a workshop setting. The large measuring span reduces the need for frequent re-positioning, increasing throughput on inspection benches. The device is designed to be mounted on standard stands and fixtures; the dial layout makes comparison against master standards intuitive. Regular calibration is recommended to maintain stated accuracy; basic maintenance consists of keeping the dial face and spindle free from contamination and checking for smooth travel.

Practical integration for measurement tasks and documentation

The indicator is suitable for applications such as concentricity control, flatness checks and thickness comparison in light to medium shop environments. The mechanical design requires no power source, which simplifies setup and avoids electrical interference concerns. Results obtained with this gauge can be documented manually or entered into quality records for trend analysis.

FAQ

What measurement accuracy can be expected from this indicator?
The dial indicator M2 / 30T (Käfer, SKU 4000851667NW) provides a reading resolution of 0.01 mm; with correct mounting and calibration, repeatable comparative readings are achieved for workshop inspection tasks.

Is the instrument suitable for runout and concentricity checks?
Yes, the instrument is designed for runout and concentricity assessments; the 30 mm span and clear dial make it suitable for rotational checks when used with an appropriate stand.

How is the dial interpreted when the pointer completes a full revolution?
One full pointer rotation corresponds to 1.0 mm, which simplifies multi-revolution readings by indicating millimetre increments per bezel revolution.

Does the device require a power supply or electronics?
No power source is required; this is a mechanical dial indicator, which reduces setup complexity and eliminates electrical interference considerations.

What routine maintenance is recommended to preserve accuracy?
Keep the dial face and spindle clean, avoid impacts, and verify performance against a calibration standard periodically; any wear or damage should be addressed to maintain the stated resolution.
