Digital Micrometer M302.293 — Digital micrometer with 75–100 mm range and 0.001 mm resolution (Metav IndustryLine)

The Digital Micrometer M302.293 is a hand-held, externally focused measuring instrument designed for precise diameter and thickness checks in production and inspection environments.

• 75–100 mm measuring range, robust spindle
• 0.001 mm resolution for fine readings
• Ratchet thimble for constant measuring force
• Four-button digital display with ABS and HOLD

Speed and accuracy that accelerate inspection

A high-resolution 0.001 mm readout shortens decision cycles during incoming inspection and final checks without sacrificing reliability. The long, clear digital display with dedicated ON/0-, mm/inch, ABS and HOLD buttons reduces operator input and read-back errors, while the compact mass supports handheld operation across repeated measurements. Used in routine quality control, this configuration reduces time per measurement and delivers consistent numeric output for traceable documentation.

Repeatable contact and robust measuring faces for dependable results

Built with a ratchet thimble to ensure constant measuring pressure, the instrument minimises operator-induced variation, which is crucial when tolerances are tight. The hardened measuring faces and a measuring face diameter of 6.5 mm support stable contact geometry and long-term wear resistance. Constructed to comply with DIN 863, the design is targeted at practical shop‑floor use and laboratory sampling, offering a dependable balance between stiffness and manoeuvrability for external measurements in metalworking and component assembly.

Digital functions that integrate with data workflows

Equipped with a four‑button interface and RB 4 data output, the micrometer enables straightforward numeric transfer into data collectors or QC software where supported. The ability to switch between mm/inch and to freeze readings with HOLD speeds documentation and reduces transcription errors, improving throughput in batch inspection and SPC tasks. The instrument’s digital logic and clear controls make it suitable for operators with basic digital experience while preserving mechanical fundamentals.

Engineered for everyday workshop and quality use

The unit’s balanced weight and ergonomic form support repeated measurements across a production shift, while the precise resolution and standards compliance allow its use for serial quality checks and sample certification. As part of a broader measuring strategy, this micrometer fits well where a durable, accurate external gauge is required and complements lab-grade instruments when fast, reliable readings are needed on the shop floor.
