From equipment tracking to uncertainty budgets, CalibrationOS gives you enterprise-grade calibration management with a free plan that actually works.
Track unlimited equipment with due dates, categories, status, barcodes, and complete calibration history. Know what's due, what's overdue, and what needs attention.
Record as-found/as-left data, environmental conditions, reference standards used, and overall results. Generate audit-ready calibration certificates.
Automatic out-of-tolerance investigations with 12-step workflow, root cause analysis, corrective actions, and impact assessment. Triggered automatically on OOT results.
Build GUM-compliant uncertainty budgets with Type A/B components, combined and expanded uncertainty, coverage factors, and effective degrees of freedom.
Conduct Gage R&R studies (crossed, nested), linearity & bias, and stability studies. Calculate %GRR, number of distinct categories, and pass/fail per AIAG MSA.
Analyze calibration drift trends over time. Predict when equipment will go out of tolerance and optimize calibration intervals based on actual performance.
SHA-256 hash-chained audit trail that cannot be altered or deleted. Every calibration, equipment change, and user action is recorded with full traceability.
Electronic signatures with meaning, PIN verification, and tamper-evident integrity hashing. Full 21 CFR Part 11 compliance for regulated industries.
Organize equipment by Site, Department, and Location. Manage multiple facilities with site-specific dashboards and cross-site reporting.
Full REST API for integration with ERP, QMS, LIMS, and MES systems. Real-time webhooks for calibration events, OOT alerts, and equipment status changes.
Email reminders for approaching due dates at 30, 14, and 7 days. Instant alerts for OOT events, investigation updates, and approval requests.
Six roles from Viewer to Owner with granular permissions. Control who can record calibrations, approve results, manage equipment, and access settings.
Yes. The Free plan includes 25 equipment assets, 1 user, and full calibration tracking with an immutable audit log. No credit card required, no time limit.
Yes. CalibrationOS has a built-in CSV importer that maps your spreadsheet columns to equipment and calibration fields with validation and error handling.
CalibrationOS is built AS9100-native. It covers clause 7.1.5 requirements including measurement traceability, calibration status tracking, and protection from adjustments that would invalidate results.
Every action is recorded in a SHA-256 hash-chained log that cannot be altered. Each entry links to the previous entry's hash, creating a tamper-evident chain similar to blockchain technology.
Free plan includes 25 assets with full tracking. No credit card required.
