About Obsidian Metra
Built for work that needs to stand up to scrutiny
Obsidian Metra is a calibration management and audit-readiness platform developed by Obsidian Reach Ltd, a British technology company building software for environments where accuracy, traceability and reliable evidence matter.
Metra was created around a simple idea: calibration management should be more than a list of equipment and a collection of due dates.
Quality teams need to know what was calibrated, how it was calibrated, which procedures and reference standards were used, what the measurements showed, who reviewed the work, and whether the evidence will still make sense months or years later when an auditor asks for it.
That's what Metra is designed to provide.
Connected evidence
Calibration records you can rely on
Metra brings equipment, calibration requirements, controlled procedures, measurement results, uncertainty, reference standards, certificates, approvals and audit evidence together in one traceable system.
Rather than treating compliance as something assembled immediately before an audit, Metra is designed to build the evidence trail as work happens.
From an individual measurement to a complete ISO/IEC 17025 audit dossier, the aim is the same: make it straightforward to understand what happened, why it happened and what evidence supports it.
The company behind Metra
Developed by Obsidian Reach
Obsidian Metra is developed, operated and owned by Obsidian Reach Ltd.
Obsidian Reach develops technology for operational and regulated environments, with a particular focus on turning complex real-world information into systems that people can understand, trust and act upon.
That engineering approach shapes Metra.
We favour explicit workflows over hidden assumptions, retained history over overwritten records, and evidence over a simple green status indicator. The result is software designed not just to tell a quality team that something is compliant, but to help them demonstrate the work behind that conclusion.
Who Metra serves
Designed for quality-led organisations
Metra is being built for laboratories, manufacturers, calibration teams and other organisations responsible for maintaining calibrated equipment and controlled measurement processes.
The platform is designed to support organisations working with requirements such as ISO/IEC 17025:2017, while recognising that software alone cannot make an organisation compliant or accredited.
Metra provides the tools, controls and evidence. Qualified people remain responsible for the technical and quality decisions behind them.
How we build
Our approach
We believe professional software should be powerful without becoming unnecessarily complicated.
That means building Metra around a few principles:
- Traceability by default — important changes and decisions should leave a clear history.
- Evidence as part of the workflow — audit preparation shouldn't mean reconstructing what happened months afterwards.
- Human accountability — automation should support qualified people, not obscure who made a decision.
- Practical compliance — controls should improve the quality of the process rather than create bureaucracy for its own sake.
- Clear, modern software — regulated software doesn't need to feel like it was designed twenty years ago.
