If you need calibration please send an email to sales@greatgages.com or you can find more information on how to reach us on our Contact Us page. Certificate of Accuracy All of our manufacturers include a Certificate of Accuracy with their Thread Gages off-the-shelf. These Certificates are statements that the gage has been verified to be accurate from the manufacturer, and that the manufacturer has used NIST-traceable gages to perform this verification. However, this is NOT a Certificate of Calibration. Certificate of Calibration None of our manufacturers include a Certificate of Calibration with their gages off-the-shelf. If the customer needs a Certificate of Calibration, that is a NIST-traceable document with verified readings, this is an additional Calibration Service that needs to be quoted with the gage. The standard lead time for a Calibration Service adds about 1-week to the lead time of the gage.
