90.62/90.75/90.87/91.00 mm Flat Glass Set For Micrometer Calibration 0.1 µm Accuracy - Metav IndustryLine

Take advantage of the combination of 0.1 µm accuracy, precise parallelism ≤ 0.006 mm and a set of four stepped reference plates to verify micrometers across the mid‑range reliably; order the plane glass set directly via Metav Werkzeuge or consult our specialists if further guidance is needed.

Plane Glass Set for Micrometer Inspection M318.228 — 0.1 µm accuracy, four plates

Plane Glass Set for Micrometer Inspection M318.228 is a compact verification kit designed for checking and adjusting micrometers in the 75–100 mm range, suitable for both workshop and laboratory environments.

• 0.1 µm certified accuracy
• Four precision plates included
• For micrometers 75–100 mm
• Parallelism ≤ 0.006 mm

Reliable reference for mid‑range micrometer checks

The set provides high‑stability reference surfaces for systematic verification of measuring instruments in the micro range. With an inherent accuracy of 0.1 µm, the plates serve as a repeatable baseline to detect wear, setting errors or mechanical drift in micrometers and screw gauges. The stepped lengths (90.62, 90.75, 90.87 and 91.00 mm) enable incremental checks across the working span, so linearity and zero‑point behaviour can be assessed without extrapolation.

Practical benefits during daily calibration routines

Supplied as a four‑piece set, the plates simplify routine inspection sequences: they allow quick stack checks and direct comparison measurements at several points within the 75–100 mm band. The stated parallelism ≤ 0.006 mm reduces uncertainty when used as an anvil reference, lowering the need for complex fixturing. For workshops seeking consistent throughput, the kit supports fast corrective actions and minimises instrument downtime by making deviations immediately visible and quantifiable.

Simple method, clear results

Use these plane glass standards to check an instrument by placing a reference plate between the micrometer anvils and recording deviations from the nominal value for each step. The set is designed for straightforward handling: its compact format and defined plate sizes reduce manipulation errors and support reproducible procedures in calibration logs. Where traceability and documented checks are required, the plates provide a robust basis for quality records and maintenance schedules.

FAQ

What accuracy can be expected from this plane glass set?
The plane glass set offers an accuracy of 0.1 µm, which allows fine detection of deviations when verifying micrometers in the 75–100 mm range.

How many plates are included and what are their sizes?
The set includes four plates with lengths of 90.62 mm, 90.75 mm, 90.87 mm and 91.00 mm, supplied together to perform stepped checks across the target range.

Can the set be used to check micrometer linearity?
Yes. By measuring across the provided plate sizes, the plane glass set enables assessment of linearity and point‑to‑point consistency for a micrometer.

Is the parallelism specification sufficient for workshop calibration?
The declared parallelism of 0.006 mm is intended to give consistent reference behaviour for routine verification and short‑term adjustments in workshop and lab settings.

Which micrometers are suitable for verification with this kit?
The plane glass set is designed specifically for micrometers with an intended measurement span of 75–100 mm and is ideal for mid‑range verification tasks.
