65.62/65.75/65.87/66.00 mm Gauge Glass Set For Micrometer Calibration 0.1 µm Accuracy - Metav IndustryLine

Take advantage of an accurately dimensioned reference set that combines 0.1 µm flatness with a compact, four‑plate layout to keep routine micrometre checks fast and reliable. The set supports verification across the 50–75 mm range and offers consistent parallelism (0.006 mm) for reproducible comparisons — order via Metav Werkzeuge or consult our team for selection advice.

M318.227 plane-glass set — optical flats for micrometre inspection, 0.1 µm accuracy (Metav IndustryLine)

The M318.227 plane-glass set is an optical reference kit for verifying micrometres in the 50–75 mm measuring range, supplied as four precision plates to check anvil parallelism and measuring consistency.

• 0.1 µm flatness for high-precision checks
• Four precision plates for 50–75 mm micrometres
• Parallelism 0.006 mm for reproducible results
• Total weight 0.5 kg for easy handling

Reliable reference for routine micrometre verification

The M318.227 set provides an economical, metrology‑grade reference for routine checks of micrometres and small measuring instruments. With a declared flatness of 0.1 µm, the plates serve as a stable, known surface against which anvil faces can be compared. This level of flatness helps to reveal wear, dirt or alignment errors that would otherwise introduce systematic measurement bias. The four plate sizes (65.62 / 65.75 / 65.87 / 66.00 mm) allow cross‑checking across a narrow band of clearances typical for the 50–75 mm micrometre class.

Controlled geometry for reproducible comparisons

Consistent geometry is central to reproducible verification: the set’s parallelism of 0.006 mm ensures that readings taken across different plates remain comparable. For workshop quality control this reduces scatter between checks and shortens decision cycles for maintenance or rejection. The plates’ compact design and total mass of 0.5 kg make handling straightforward while maintaining sufficient rigidity to avoid bending during short inspection routines. The result is a practical balance of stability and portability for bench‑level metrology.

Micro-class suitability for fine mechanical work

Classified for the Micro category (measuring range 50–75 mm), this reference kit is tailored to fine mechanical and precision‑assembly environments where space is limited and accuracy matters. The set fits the workflow of tool rooms, small‑parts assembly and repair benches, enabling quick verification without specialised fixtures. Each plate performs as a precision reference to confirm that the measuring instrument remains within its expected behaviour, supporting traceable quality procedures in small to medium production runs.

FAQ

What measuring range is this set intended for?
The set is intended for verification of micrometres in the 50–75 mm measuring range; the plate sizes are matched to that band for comparative checks.

How precise are the reference plates?
The M318.227 plane-glass set is specified with a flatness of 0.1 µm and a parallelism of 0.006 mm, providing a high‑precision reference for micrometre checks.

How many plates are included and what are their sizes?
The kit comprises four plates with nominal sizes 65.62, 65.75, 65.87 and 66.00 mm to permit consistent cross‑comparisons within the intended range.

How should the plates be used to check a micrometre?
Compare the micrometre anvil against a plate surface, record any deviation from the expected reading and repeat across at least two plates to confirm repeatability; use gentle, consistent contact to avoid introducing measurement error.

Is the M318.227 suitable for shop‑floor and small lab use?
Yes. Its compact dimensions and controlled geometry make it suitable for bench‑level quality checks in tool rooms, small assembly operations and precision workshops.
