End gauge 250 mm – Grade 0 reference length, DIN EN ISO 3650 (Metav IndustryLine)

The End gauge 250 mm is a precision reference for length verification and inspection tasks in calibration shops and production quality control.

• Grade 0 accuracy to DIN EN ISO 3650
• 250 mm calibrated reference length
• Hardened special steel construction
• Compact 35 x 9 mm cross-section

High‑precision reference that speeds up quality checks

This Grade 0 reference conforms to DIN EN ISO 3650, providing a reproducible baseline for length verification in production lines and inspection benches. The tight tolerance class reduces uncertainty when comparing measuring instruments, which in turn lowers the need for repeated measurements and rework. By working with a standardised reference length instead of improvised gauges, measurement routines become more consistent, and process throughput is improved without compromising traceability.

Durable design for repeatable measurements over time

Constructed from hardened special steel and featuring a slim 35 x 9 mm cross‑section, the gauge combines surface resistance with manageable mass. The robust material choice ensures wear resistance under frequent use, while the compact profile preserves rigidity across the nominal length. For workshops that require both handling convenience and reproducible contact conditions, this balance of hardness and form factor gives dependable results across daily inspection cycles.

Practical integration with inspection equipment and workflows

Designed as a fixed length standard, the end gauge serves as a quick reference for checking calipers, micrometers and similar instruments used in routine quality control. The clearly specified nominal length and tolerance enable technicians to validate instrument function swiftly, reducing downtime associated with uncertainty checks. As a physical benchmark, it supports traceable verification steps that complement statistical process control and documented inspection procedures.
