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.
