We bought a new Omega Digital Temperature Meter (HH912T). The unit came with an Omega "Certificate of Calibration". The cert contains the "Model and Serial #s", "Date", "Tested By" and has a space for "Authorized Signature" (no one signed in this space). There is no data whatsoever yet the cert states its calibration is traceable to NIST. There are no ID numbers on this card relating to any cal. Is this an acceptable calibration cert in the medical device space? I said no and was disagreed with - the unit went into production. Can someone help me regarding my stance that this "cert" is inadequate? I want to send it out to a real calibration service provider for a real calibration with data and traceable to NIST.
