Everything You Need for Calibration Management

From equipment tracking to uncertainty budgets, CalibrationOS gives you enterprise-grade calibration management with a free plan that actually works.

Equipment Tracking

Track unlimited equipment with due dates, categories, status, barcodes, and complete calibration history. Know what's due, what's overdue, and what needs attention.

Calibration Records

Record as-found/as-left data, environmental conditions, reference standards used, and overall results. Generate audit-ready calibration certificates.

OOT Investigations

Automatic out-of-tolerance investigations with 12-step workflow, root cause analysis, corrective actions, and impact assessment. Triggered automatically on OOT results.

Uncertainty Budgets (GUM)

Build GUM-compliant uncertainty budgets with Type A/B components, combined and expanded uncertainty, coverage factors, and effective degrees of freedom.

Gage R&R / MSA

Conduct Gage R&R studies (crossed, nested), linearity & bias, and stability studies. Calculate %GRR, number of distinct categories, and pass/fail per AIAG MSA.

Drift Analysis

Analyze calibration drift trends over time. Predict when equipment will go out of tolerance and optimize calibration intervals based on actual performance.

Immutable Audit Log

SHA-256 hash-chained audit trail that cannot be altered or deleted. Every calibration, equipment change, and user action is recorded with full traceability.

E-Signatures (21 CFR 11)

Electronic signatures with meaning, PIN verification, and tamper-evident integrity hashing. Full 21 CFR Part 11 compliance for regulated industries.

Multi-Site Management

Organize equipment by Site, Department, and Location. Manage multiple facilities with site-specific dashboards and cross-site reporting.

REST API & Webhooks

Full REST API for integration with ERP, QMS, LIMS, and MES systems. Real-time webhooks for calibration events, OOT alerts, and equipment status changes.

Automated Notifications

Email reminders for approaching due dates at 30, 14, and 7 days. Instant alerts for OOT events, investigation updates, and approval requests.

Role-Based Access Control

Six roles from Viewer to Owner with granular permissions. Control who can record calibrations, approve results, manage equipment, and access settings.

Frequently Asked Questions

Is CalibrationOS really free?

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.

Can I import data from spreadsheets?

Yes. CalibrationOS has a built-in CSV importer that maps your spreadsheet columns to equipment and calibration fields with validation and error handling.

Does CalibrationOS meet AS9100 requirements?

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.

How does the audit trail work?

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.
