M302.277 digital outside micrometer — 75–100 mm, IP65 (Metav IndustryLine)

A M302.277 digital outside micrometer designed for accurate external measurement of shafts, bushings and turned components in workshop and inspection environments

• 1 µm digital resolution
• IP65 dust and splash protection
• Ratchet stop for constant measuring force
• Supplied in protective case

Precision where repeatability reduces rework

The instrument delivers 1 µm (0.001 mm) resolution on a clear digital readout, enabling tight tolerance checks and decisive go/no‑go evaluations on production parts. Built to DIN 863 standards, the device combines a robust frame with a finely machined spindle so that each measurement is directly comparable—minimising rework and accelerating inspection cycles. The 75–100 mm measuring range places the instrument in the standard workshop category, offering a practical balance of reach and stiffness for everyday machine‑shop tasks.

Built to perform on the shopfloor

Designed for practical industrial use, the micrometer features IP65 protection against dust and water jets and a matt‑chromed measuring drum for low glare and long life. A built‑in ratchet stop provides a consistent measuring force, reducing operator‑dependent variation and improving repeatability across series checks. The measuring faces are hardened and precisely ground, Ø 6.5 mm, to resist wear and to keep contact geometry stable over thousands of cycles—ensuring reproducible results on components made of steel, aluminium and similar materials.

Intuitive handling and clear traceability

The digital display includes ON/OFF, ABS/INC, SET and UNIT functions for straightforward operation and quick switching between metric and other units where relevant. The painted frame and matt‑chrome measuring drum combine tactile durability with corrosion resistance, while the ratchet and ergonomic thimble support comfortable, fatigue‑free measuring. Supplied in a protective case for safe transport and storage, the instrument is ready for immediate use on the bench. The instrument is identified by SKU M302.277 and GTIN for stock control and traceability.
