Temperature logging with audit trails for vaccine refrigeration, lab freezers, and transport. Compliance-grade records, zero operator effort.

The problem

A clinical facility needed continuous temperature monitoring across vaccine refrigeration and lab freezers, with audit-ready records that would stand up to regulatory review. Manual logbooks were error-prone and a legal liability.

What we built

Calibrated temperature probes with cellular gateways that survive building power loss, an immutable audit log, and compliance reports generated automatically on the cadence the regulator wants.

The outcome

Zero missed readings over 18 months of operation. Audits take an afternoon instead of a week. Ops team stopped copying numbers into spreadsheets.
