Digital Micrometer M302.285 — 25–50 mm, IP65, 0.001 mm (Metav IndustryLine)

The Digital Micrometer M302.285 is a workshop-grade micrometer designed for high-precision external measurements in the 25–50 mm range, combining a sealed indicator, fine spindle control and a clear digital readout for quality control and production inspection.

• IP65 protection for dust and splash resistance
• 0.001 mm resolution for 1 µm readings
• Friction ratchet ensures consistent measuring force
• ON/OFF, ABS/INC, SET and UNIT display functions

Built for repeatable precision on the shop floor

The Digital Micrometer M302.285 brings workshop robustness to routine dimensional checks. With a measuring range of 25–50 mm, a 0.001 mm display step and hardened measuring faces, the instrument is aimed at inspection stations and assembly benches where repeatability matters. The friction ratchet helps to guarantee a consistent closing force, which reduces operator-induced variation and improves the comparability of successive readings. Compliance with DIN 863 positions the device within recognised mechanical metrology practice, making it suitable for incoming inspection and production control.

Faster readings, fewer handling errors

The sealed digital display supports ON/OFF, ABS/INC, SET and UNIT functions, enabling quick toggling between absolute and incremental modes and simple zeroing for batch inspection. The spindle pitch 2 mm gives fine thread movement for precise approach, while the matt‑chrome measuring drum and tactile ratchet aid controlled handling. Together these features increase throughput: measurements are taken more quickly and with reduced rework, supporting efficient quality workflows without sacrificing measurement integrity.

Robust construction for everyday use

Designed for the realities of the production environment, the micrometer’s frame is painted and the measuring drum is matt chrome finished to resist wear and maintain legibility. The instrument is rated IP65, so it tolerates dust ingress and wash-downs typical in busy shops. The presence of hardened measuring faces protects contact surfaces and extends service life under frequent use. These construction choices, combined with a compact 25–50 mm span, deliver a balance of stiffness, manoeuvrability and durability that suits metrology benches and machine-side inspection alike.

FAQ

Is the micrometer suitable for routine shop-floor use?
Yes. The Metav IndustryLine digital micrometer M302.285 is designed with IP65 protection and durable finishes to withstand dust and splash exposure typical in production environments.

What level of resolution and repeatability does it offer?
The instrument provides a display resolution of 0.001 mm (1 µm), giving fine graduated readings that are valuable for precise dimensional control with consistent repeatability when used with the friction ratchet.

Does the device comply with recognised metrology standards?
The product is specified to meet DIN 863, which aligns it with established mechanical metrology practices for external micrometers.

Why is the 2 mm spindle pitch important?
A spindle pitch of 2 mm offers controlled spindle advance and tactile feedback on each rotation, improving the operator’s ability to close the anvils precisely and reducing the risk of over‑travel during measurement.

Are the measuring faces protected against wear?
Yes, the micrometer features hardened measuring faces, which increase resistance to wear under frequent contact and contribute to longer service life for the instrument.
