I have had considerable difficulty getting FAA authorized oxygen service stations to retest and refill my 22 cu. ft. steel tank

If there is a Technical Dive Shop in the area they may be able to help
you. A Technical Dive shop will do custom mixing of gases including
Helium and Oxygen for deep dives. Yes, they have the same DRY oxygen
we have. Think about having a regulator freeze up at 300 feet below
in the water. Locally we have a Technical Dive shop and they fill my
tank in a matter of minutes, just carry it in. I think the last time
they charged me about $3.50. They also recently started doing the
pressure test. Also a Gas supply house for oxygen systems, should be
able to do your testing and refill. ( about $35 the last time I went
there) Locally the quickest and cheapest is the Dive shop. Yes, they
have an impressive manifold system and give you 100% oxygen.
