Metralis
A new class of coordinate measurement technology — built on decades of National Physical Laboratory expertise and designed for the factory floor.
What is Metralis?
Fast, trustworthy measurement — without the trade-offs
Today's measurement systems force a choice: speed or accuracy, flexibility or traceability. Metralis removes that compromise. It measures multiple targets at once, provides real-time performance data (measurement uncertainty), and ties every result directly to the SI metre — giving you measurement you can act on with confidence.
How Metralis works
Four capabilities that set Metralis apart
Measure multiple targets simultaneously
Metralis captures many points at once with high accuracy, replacing slow point-by-point routines and keeping production moving.
Self-calibrating, with systematic error correction
The system continuously corrects for systematic errors and keeps itself calibrated — removing a major source of uncertainty and downtime.
Direct traceability to the SI metre
Measurements trace directly to the international standard of length, so your data is defensible and audit-ready by design.
Real-time performance indicator
A live confidence indicator tells you the measurement is right as it happens — no waiting, no second-guessing the data.

In the real world
Proven in a live manufacturing environment
Metralis is not a concept. It is in active development at AMRC Cymru — one of the UK's leading advanced manufacturing research centres — where it measures real aerospace structures alongside industrial robots and production tooling.
