Digital internal dial indicator M209.133 – 20–40 mm, 0.005 mm resolution (Metav IndustryLine)

The Digital internal dial indicator M209.133 is a compact electronic inside probe for fast measurement of bores, slots and internal features in workshop quality control and small-series inspection.

• Fast measurement of bores and grooves
• High resolution 0.005 mm
• Measuring range 20–40 mm

Precision where small deviations matter

The instrument delivers a resolution of 0.005 mm, enabling reliable detection of fine deviations in small bores and machined slots. With a stated measuring accuracy of 0.03 mm, the device is suitable for routine quality-control tasks in metalworking and precision assembly where repeatable results are required. The round measuring tips R0.5 reduce marking on workpiece surfaces and ensure consistent contact geometry, which helps to avoid measurement artefacts that can occur with blunt probes.

Designed for efficient workshop inspection

A rotatable display with ON/OFF/SET, ABS/INC/UNIT, TOL and MODE controls simplifies reading orientation and allows switching between absolute and incremental modes as well as unit selection. This speeds up inspection cycles and reduces handling time during series checks. The compact construction and a weight of about 0.7 kg make the instrument easy to position in fixtures or by hand, while the 20–40 mm range covers the typical bore sizes encountered in tooling, maintenance and small-part production.

Robust handling and transport for everyday use

The indicator is built for practical workshop use: the electronics are integrated into a secure housing and the set is supplied in a protective case for transport and storage, which reduces the risk of shock or contamination during handling. Clear mechanical design and durable probe tips support repeatable measurements even under frequent use, which contributes to lower inspection cycle times and fewer re-measurements on the shop floor.
