Free calibration certificate template
A certificate of calibration with the fields an auditor expects: as-found and as-left results, measurement data with tolerances, reference standards with their own certificate numbers, and a signed statement. A completed example is included.
.xlsx · Works in Excel, Google Sheets and LibreOffice · No signup, no watermark.
From the completed example certificate that ships in the file, marked as fictional throughout.
What’s inside
Identification
Certificate number, control, serial and asset numbers, and the instrument details: type, manufacturer, model, range and accuracy. The unique IDs an auditor follows from your register to the document.
Results and measurement data
As-found and as-left condition as dropdowns, adjustments and repairs, fit for purpose. The measurement table computes Pass or Fail from nominal, tolerance and the as-left value, and you can always type over it.
Traceability
The reference standards you calibrated against, each with its own certificate number and the institute the chain ends at. The unbroken chain is what makes a certificate defensible.
Statement and sign-off
A pre-written calibration statement you can edit, the procedure reference, and signature lines for the technician and the approver. Next due is calculated from the date and interval.
The one thing this template can’t do is set the page.
The fields are all here, but the logo, the clean layout and the consistent numbering are still on you every single time. Our free certificate generator fills these exact fields in your browser and returns a print-ready PDF with your logo on it. No login, and your data never leaves the browser.

Common questions
What should a calibration certificate include?
An auditor expects: the instrument's identity (control and serial numbers), the date calibrated and the next due date, as-found and as-left results, the reference standards used with their own certificate numbers, who performed the calibration, and a signed statement. This template has a field for each, and the minimum set is marked with an asterisk.
Does this replace an accredited calibration certificate?
No. If a customer or regulation requires ISO/IEC 17025 accredited calibration, that certificate must come from an accredited laboratory. This template documents calibrations you perform in-house, which is what ISO 9001 clause 7.1.5 asks of most workshops.
How does the Pass/Fail column work?
When nominal, tolerance and the as-left value are all numbers, the Result cell computes Pass if the as-left value is within nominal ± tolerance, otherwise Fail. It is the same rule our free certificate generator uses, and you can type over the result at any time, for example for text readings.
Is it really free?
Yes, and no email is required. The file includes a completed example certificate with clearly fictional data so you can see how every field is meant to be used. We make Gaugelog, calibration management software, and hope you'll think of us when the certificates start piling up.
Want the whole register to keep itself?
The template is yours either way. When Gaugelog launches, every certificate lives on its instrument, and reminders fire before anything goes overdue.
One email when Gaugelog launches. Nothing else, ever.
