Calibration tracking software
Track every gauge, its due date and its history in one register. Escalating reminders at 30 days, 14 days, 7 days and on the due day. When the auditor asks, you answer with documents, not memory.
The short version
Calibration tracking is one loop: know what you own, know when each item is due, calibrate on time, and keep the evidence. Gaugelog runs that loop as a register with due dates, escalating email reminders, calibration records with as-found and as-left results, and an audit pack you can export on any plan. It is built for ISO 9001 shops with roughly 150 to a few thousand instruments. Under about 150, a well-kept spreadsheet can honestly do the job; start with the free log template and come back when it stops scaling. Details checked 11 July 2026.
What tracking actually takes
Five questions decide whether a tracking system works. Here is how Gaugelog answers each one.
What do we own, and what state is it in?
A register with a control number, serial number, type, location and status for every instrument. Eight statuses cover the real fleet, from active to out for calibration to retired, and retired instruments keep their history but leave the due list.
When is each one due?
Every instrument carries its calibration interval and a computed next due date. The schedule updates from the record you log, not from a cell someone remembers to edit, so the register and the history can never disagree.
Who finds out, and when?
Escalating email reminders at 30, 14 and 7 days before the due date and on the day itself, then weekly for as long as an instrument sits overdue. One digest per recipient, never one email per instrument, and every send is written to a delivery log.
What happened at the last calibration?
Each record stores who calibrated, the as-found and as-left results and the certificate. A failed as-found opens a documented out-of-tolerance cascade: product impact, who was notified, corrective action, and a required closure.
Can we prove all of this later?
Every change is written to an append-only audit trail, enforced in the database. The audit pack exports the register, due list, calibrations, out-of-tolerance events and on-time rate as one PDF.

If the file is not open, it cannot warn you. That is the whole failure mode: due dates live in a sheet nobody checks between audits, and the overdue list is discovered by the auditor. Gaugelog sends the reminder whether or not anyone has logged in, and you can send yourself a test alert on day one, before you have to trust it.
Start from the spreadsheet you already have
Upload the file as it is. Messy columns are fine: the mapper reads your column headers and suggests a mapping, you confirm it, and rows of past calibrations import as history. Import uses AI once, to read your column headers. Everything after that is deterministic. No AI touches your records.
Everyone can check. No one pays to look.
Unlimited users on every plan, including Free. The operator who wants to know whether a caliper is safe to use looks it up; nobody files a license request. Tracking systems fail when only one person can see them.
See the plansWhat Gaugelog doesn’t do
- No measurement uncertainty calculations. If you run an ISO 17025 lab, you need more math than Gaugelog does.
- No on-premises install. Gaugelog is cloud software hosted in the EU, with full export on every plan: cancel anytime, export everything.
- Under roughly 150 instruments, a well-kept spreadsheet is honestly fine. Start with the free calibration log template and come back when it stops scaling.
What your auditor sees
Overdue gauges are the first thing an auditor checks. When they ask, you answer with documents, not promises. Both samples below are generated by Gaugelog from fictional data.

What is calibration tracking software?
Software that keeps an instrument register with calibration intervals and due dates, sends reminders before instruments fall overdue, stores the calibration records and certificates, and exports the evidence an auditor asks for. The difference from a spreadsheet is that it acts on its own: reminders fire whether or not anyone opens a file.
Can I keep using my spreadsheet as the starting point?
Yes. Upload it as it is. The mapper reads your column headers, you confirm the mapping, and history rows import as calibration records. A messy 200-row sheet typically takes under ten minutes from file to register.
What does it cost?
Free up to 30 gauges with unlimited users. Paid plans run from $49 to $379 per month billed annually, set by gauge count, never by seat count. No hidden fees. Ever.
What happens when an instrument goes overdue?
It moves to the top of the digest and stays there: reminders repeat weekly by default, daily or monthly if you prefer, until a calibration is logged. Retired and lost instruments never trigger reminders.
Will my auditor accept the records?
Auditors check the record chain: register status, due dates, history, out-of-tolerance decisions and certificates. Gaugelog exports all of it as one audit pack. Download the sample on this page and show it to your auditor before you commit.
Weighing your options before the audit?
Gaugelog is in development and launches in 2026. Until then you can generate a clean calibration certificate PDF with our free tool, no account needed, and compare the plans on the pricing page.
