Metav IndustryLine Digital disc micrometer ND 25–50 mm, 0.001 mm resolution

The Digital disc micrometer ND 25–50 mm, 0.001 mm is a compact precision instrument for dimensional inspection of small components in production, laboratory and workshop environments.

• High precision 0.001 mm resolution
• Measurement range 25–50 mm
• Ratchet stop for consistent force
• Digital display with ABS/INC and unit keys

Consistent metrology for process control

The micrometer offers a resolution of 0.001 mm combined with a stated accuracy of 0.004 mm, providing measurable gains in repeatability for routine quality checks. This level of resolution supports tighter tolerance verification than standard 0.01 mm instruments and reduces uncertainty when documenting small-diameter features. The digital readout with ABS/INC switching and unit selection speeds up reading and reduces transcription errors, while the RB 4.1 data interface enables direct transfer of measurement results into inspection software or SPC systems, minimising manual input and accelerating reporting.

Design elements that reduce operator influence

Engineered for reliable handling, the frame is painted for corrosion resistance and the measuring drum is matt-chrome plated to ensure a smooth spindle action. A non-rotating spindle and integrated ratchet stop enforce a consistent measuring force, which lowers variation between operators and enhances comparability across shifts. At approximately 0.9 kg, the device balances stability and manoeuvrability for bench use; the repeatable mechanical features reduce the influence of handling on the measurement outcome.

Data workflow and traceability in inspection routines

The micrometer’s digital output (RB 4.1) facilitates automated data capture for traceable inspection records and helps integrate the instrument into a digital quality system. Identifiers such as GTIN and classification metadata support procurement and inventory tracking, while the compact readout functions (ON/OFF, ABS/INC, UNIT, SET) simplify calibration checks and unit conversions. These traits make the instrument suitable where documented measurement trails and quick logging are required, for instance in incoming inspection or final part verification.

Typical applications and user groups

With a measuring span of 25–50 mm, this instrument is aimed at component manufacturers, toolrooms and laboratory technicians who require exact measurement of small shafts, rings, bores and turned parts. Its combination of fine resolution, mechanical consistency and straightforward digital linking is particularly useful in production environments that demand frequent, repeatable checks without the complexity of larger metrology equipment. The overall package supports efficient in-process control as well as final acceptance testing.
