ISO 9001 asks you to keep measuring equipment calibrated, traceable and identified (clause 7.1.5). In most workshops that lives in a spreadsheet nobody opens until something is already overdue.
The register shows what is overdue, due soon, failed or never calibrated, the most urgent first. Nothing to sort or colour by hand.
The team gets one short list of what needs a calibration, a month ahead (you choose how far). Nothing due, no e-mail.
Attach the lab's PDF to each calibration. The auditor asks for C-014's certificate: two clicks.
Every instrument, its last calibration, certificate, result and due date on one printable page, ready to sign.
Import a CSV from the spreadsheet you have now: Gaugebook reads the usual column names. Export it back any time.
A failed calibration marks the instrument until it is repaired or taken out of service, so nobody measures with it.
No installation, no training. It runs in the browser on any computer, tablet or phone.
Type them in, or import your current list. Give each its interval: 12 months for most calipers and micrometers.
When an instrument comes back from the lab: the date, the result, the certificate. The next due date follows.
The weekly e-mail and the red and orange marks do the rest. Print the list when the auditor comes.
Cheaper than one missed calibration in an audit.
For a small workshop.
For the whole company.
Gaugebook keeps the records clause 7.1.5 asks for: each instrument identified, its calibration status, its calibration history and certificates, and what to do when one fails. Your auditor still looks at your whole quality system, but this part will be in order.
No. Your calibration lab (or your own procedure) calibrates; Gaugebook keeps track of when, with what result and certificate, and reminds you when the next one is due.
On Cloudflare's servers in Europe. You can export the whole register as a CSV at any moment, and delete your account and everything in it.
Any time, from the next month. Your register stays readable on the free plan; above 25 instruments you cannot add more until you go back down or upgrade again.
