Has anyone had any experience calibrating a Tomey SP-3000 pachymeter? (Or any other brand of pachymeter?) This model has a self calibration function, but I can't find any mention of calibration or verification with an external artifact of any kind.

This would be more in the medical equipment field but I figure some of you may have worked in that area at some time in your careers.

I'm not knowledgeable on this, but a brief look appears that it is ultrasound thickness measurement.  This is a similar technology to coating thickness monitors.  You'll probably need to get some thickness artifacts in the range of the Pachymeter (looks like it also goes by "Pachometer").  The other critical spec looks like the ultrasonic operating frequency appears to be 50 MHz.  What ever artifact you buy would need to properly respond to that frequency.  Just my two cents.  Fascinating technology, though.
"I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind."
