Calibration tracking software
Your calibration spreadsheet is one forgotten cell away from a nonconformity.
CalRegister is the calibration register for small machine shops and calibration labs. Same register, with a due-date engine, a certificate vault, and an audit pack.

The same instruments. One is auditable. Illustrative data.
What changes
The register stays. The scramble goes.
Six jobs an auditor tests. Each one moves from a manual habit to a record the product keeps.
| The job | Spreadsheet + binder | CalRegister |
|---|---|---|
| Is it current today? | A cell someone remembered to edit. | Calculated from the last calibration plus the interval, every day. |
| Which certificate? | A filename in an email thread from March. | Attached to the calibration event. One click from the instrument. |
| Who changed the date? | An overwritten cell. No trail. | Append-only history: who changed what, and when. |
| What is due next? | A calendar reminder, if someone set one. | A due list 30 days out, plus one digest per recipient. |
| Can the auditor look? | Screenshots and a shared folder. | A read-only seat or share link that cannot change records. |
| Can I hand over evidence? | A day of compiling PDFs. | One export: register, due list, history, certificate index. |

FAQ
Questions before the trial.
If your question is about the quality system rather than the register, this is probably not the tool for it.
Can I import my Excel register?
Export the sheet to CSV or XLSX. You map the columns, preview every row, then commit. Nothing is written until the row count and required fields check out.
Does it hold ISO 17025 records?
It holds what an auditor asks to see: date, lab or technician, result, as-found and as-left readings, adjustment, and the certificate. It does not replace the records your calibration lab keeps.
Can an auditor use it without changing anything?
Yes. The read-only auditor role can browse the register, calibration history, and certificates you share. They cannot edit, delete, or retire an instrument.
What does it not do?
No uncertainty budgets, MSA or Gage R&R, guard-banding, label printing, crib management, work orders, or ERP integration. CalRegister tracks calibration and the evidence behind it.
Start with the register you already have.
Import the spreadsheet, check the due list, and let the reminders do the chasing.
