Glass ruler M910.256 — soda‑lime glass, 0–200 mm graduations (Metav IndustryLine)

Glass ruler M910.256 for accurate workshop and optical checks, featuring fine 0.1 mm scale and a compact 230 mm form factor

• Soda‑lime glass construction for optical neutrality
• Measurement range 0–200 mm for standard workshop tasks
• 0.1 mm scale for detailed alignment and calibration
• Accuracy specified as (1.5+2L/1000) µm for traceable checks

Precision that supports reproducible inspection

The gauge delivers a combination of fine graduations and a clearly stated accuracy formula, allowing engineers and technicians to assess measurement uncertainty at a glance. The specification (1.5+2L/1000) µm expresses the instrument’s deviation relative to length, which is useful when planning tolerances and validation steps. When used for optical tasks such as scale checks or alignment under microscopes, the ruled surface and transparent substrate minimise parallax and allow consistent readings. This rational clarity supports faster decision-making in quality control.

Tough, stable material for reliable everyday use

Manufactured from soda‑lime glass, the rule offers optical stability and a smooth measuring edge that resists wear compared with coated alternatives. Its overall dimensions—230 mm length, 30 mm width and 5 mm thickness—provide a balance of reach and rigidity, reducing flex during handling. At approximately 0.08 kg the instrument is lightweight yet steady in the hand, making repetitive inspection and marking tasks less fatiguing. The clear engraving of the 0.1 mm scale ensures legibility in workshop lighting without the need for magnification.

A measuring range tailored to routine metalworking needs

With a measuring range of 0–200 mm, the instrument fits the Standard class used across machine shops and metalwork environments: it covers the common 150/200/300 mm intervals while retaining good stiffness and one‑hand usability. For tasks such as component alignment, optical scale calibration and simple profile checks, the range is large enough for most fixtures yet compact for bench use. The rule’s format supports quick comparisons and transfer measurements without introducing the handling complexity of larger gauges.

Practical care and use in inspection workflows

The glass surface is best handled with soft cloths and gentle cleaning agents to preserve the graduation and edge geometry. When stored flat and protected from hard impacts, the rule maintains its optical and dimensional integrity over long periods. For traceable workflows, record the instrument’s identifier (SKU) in calibration logs to link measurements to the correct reference. Its clarity and minimal thermal mass reduce measurement drift during short inspection tasks, supporting efficient in‑process checks.

FAQ

What materials is the glass ruler made from and why does it matter?
The glass ruler M910.256 is made from soda‑lime glass; this material provides optical neutrality and a stable, wear‑resistant surface that supports reproducible readings during optical checks and workshop use.

Is the accuracy specification suitable for routine quality control?
Yes. The accuracy expressed as (1.5+2L/1000) µm shows how the permissible deviation scales with length, making the M910.256 appropriate for standard quality control and alignment tasks where traceable tolerances are monitored.

Can this rule be used for microscope calibration or optical scale checks?
The ruled surface and fine 0.1 mm graduations of the M910.256 make it well suited to alignment and scale verification tasks performed under microscopes or loupe inspection.

How should the instrument be stored and cleaned to preserve accuracy?
Store the rule flat and protected from impacts; clean with a soft cloth and mild solvent if needed. Avoid abrasive cleaners to preserve the engraved graduations and measuring edge.

What identifier should be recorded in calibration or inspection logs?
Use the SKU M910.256 and the GTIN 4061905449017 when logging calibration or inspection entries to ensure traceability.
