RE: Small OD Tube External UT Device
We had a small diameter med freq sensor and a med size lower freq one for doing tube from 3/16"x0.012" thru 4"x0.225".
Up to about 0.050" wall we trusted it to 0.0001".

If you go to them with that info they will recommend probes.
We used official couplant goo, other things work (like KY) but you would be surprised to know how much chloride is in a lot of products.
But some spare tips (delays) for your probes, as they get worn or damaged it be harder to get good readings.
Have a couple of ref pieces, ours were about 2" long and hung from the device on a cord. It lets operators know that everything is working fine.
