Per-type calibration health
One arc gauge per equipment type: the fraction of that type's items currently OK, due soon, or overdue. A short green fill and a long red fill means that type needs attention.

This is a record-keeping tool for tracking calibration/certification due dates only - it does
not verify that any tool or piece of equipment is actually accurate, safe, or fit for
purpose, and it is not a substitute for a proper calibration/certification programme,
manufacturer guidance, or regulatory compliance requirements (for example LOLER for lifting
equipment).
By type
Every equipment type in use, sorted so types needing attention surface first.
