Certificate check
Verify a calibration certificate
Scan the QR code on the calibration sticker, or type the certificate number below. No account, no app, and nothing to install — this page is for whoever is holding the instrument.
What you will see
The certificate number, what the instrument is, when it was calibrated, when that calibration runs out, and which laboratory issued it. That is enough to know the document in your hand is genuine and still current.
What you will not see
Never the readings, never the owner’s other instruments, never a price, and never a contact name. If you are checking a certificate you are usually a third party the owner handed a document to — entitled to know it is real, not to read their file. A certificate that has not been issued reports the same as one that does not exist.
