CONTROLLED INPUTS
Versioned uncertainty budgets
Combine Type A and Type B components, distributions, sensitivity coefficients and coverage factors without rewriting historical calculations.
Obsidian Metra connects equipment, calibration work and technical evidence in one traceable system, from the next due date to the final audit dossier.
Built for teams where measurement confidence matters.

One operational record
Turn recurring requirements into a clear, accountable calibration plan.
Guide technicians through approved procedures and preserve the evidence they create.
Connect traceability, uncertainty and decision rules to every approved outcome.
Assemble audit dossiers from records already captured during normal work.
The work, not just the record
Move beyond entering a result after the event. Give technicians the controlled method, reference context and evidence prompts they need while calibration is happening.
Ordered steps, required responses and evidence checks keep the method visible at the bench.
Record the standard actually used and assess its calibration state, capability and restrictions.
Freeze the relevant revisions and evidence before an approved result becomes part of the audit history.
A result with its reasoning intact
Metra preserves the controlled calculations and decisions that make a reported result understandable later.

EXPLAINED OUTCOME
Connect measured error, uncertainty, tolerance and boundary policy so reviewers can see why conformity was assigned.
A clear working path
Context carries forward instead of being re-entered or reconstructed at every stage.
Equipment, ownership and deployment history
Requirements, intervals and due status
Controlled procedures and measurement evidence
Uncertainty, conformity and approval
Certificates, audit trails and dossiers
Evidence without the document chase
Choose the client or internal sites and reporting period. Metra freezes the scope and assembles relevant assets, work, certificates, traceability, quality records and audit history.
Obsidian Metra supports ISO/IEC 17025 evidence management. It does not confer accreditation or guarantee compliance.
Made for measurement-critical teams
Keep procedures, standards, technical evidence and approvals connected.
Control production and test equipment across sites, lines and departments.
Build clear equipment histories for quality review and audit preparation.
Make measurement decisions traceable from asset to approved result.
Make every calibration easier to find and defend
