If he's wanting to check for a particular aluminum temper, he's looking for
a conductivity meter that reads in %IACS(It's really an eddy current machine
but easier and faster to use for that function, and temper is only assured
when you have the desired conductivity and the desired hardness
together.Maybe ebay or some NDT shop.

A customer called me today looking for what he called an Eddy Current
tester.

As he described it to me, its a device that uses electronic magic to
test the hardness of a material, its thickness and so forth. He
wants it to double check heat treating.

Any idea of where to find a reasonably priced used one?
