Instrument register
Find any gauge, caliper, micrometer or test instrument in seconds. See its ID, location, status, owner and full calibration history together.
Schedules & alerts
See what is due now and next. Gaugelog calculates due dates and emails reminders at 30, 14 and 7 days, on the due date, then weekly while overdue.
Calibration records
Keep as-found and as-left readings, pass or fail decisions, the calibrator, reference standards and attachments together.
Certificates
Generate calibration certificate PDFs with your own logo and numbering, then keep each certificate linked to its instrument.
Excel import
Import your existing register and supported calibration history from Excel or CSV. Review the suggested column mapping before Gaugelog adds anything.
Audit trail
See who changed what and when. Export the register, due list, calibration history and out-of-tolerance events as one audit pack.

The register
See every gauge with its status and next due date. Filters count what needs attention and surface overdue instruments immediately.

A failed calibration, handled
As-found fail, as-left pass after adjustment. The out-of-tolerance questions are answered on the record, and the event is closed with a name and a date.

The audit pack
One button on the Reports page: register status, due lists, the period's calibrations, OOT closures and the certificate index in one PDF.
