The vacuum cleaner pulled out a bit more.
From what I can see, the lower half of the tank appears to be mostly rust free, with minimal pitting. Most of the corrosion is in the top half of the tank, not what I expected. None of it looks serious, but feel free to disagree.

Could you use an ultrasound thickness measurer maybe...think they can be had pretty cheap these days.
Even if it's not 100% accurate it might allow you to compare the good half with the bad to get a rough idea of how much thickness has left the building so to speak.

I'm not sure about that. I know paint thickness measuring tools are available, but cheap tools to measure thickness of a tank?

Buy cheap, buy twice
Is that a Henry vacuum? If so they're not made for wet vacuuming. The air you suck in is blown through the motor windings to cool it. Suck in some water and your motor could release the magic smoke!

There are cheap UT machines out there, just had a look on ebay, £22 from China!! for a one off these might do the job, certainly need some material of a known thickness as a check to make sure its throwing the numbers back at you that are correct, or as near as its going to be, the issues you have are, the paint needs removed and to hit the thinnest part of a pit with a measuring probe is not the easiest thing to do, it would just be luck, the flaw detection UT machines are in different league and allows the user to scan a surface pin pointing pitting.
It's Henry's bigger brother, Edward. Paid £3.00 for it about 8 years ago and still putting up with abuse.
Would JB Weld be a suitable alternative?Cut it in half, measure thickness and if acceptable, weld back together - simples!
Anyway, AliExpress looks cheaper than eBay. Still not sure a purchase is necessary. Mind you, my other compressor is 30 years older than this one.

The tank with the rust to the top doesn't look good. Mapping the thickness (if you already had the right gear) maybe an option.
But these modern tanks don't have much redundancy when it come to thickness..if your going to use it and not stood next to it all day and its away from others then I guess thats your call.

All these tools/instruments are useful but not definitive tests for safety. Pin holes are, by definition, zero thickness and tiny. They may occur at thin sections but can be local spots elsewhere.
Cheap, modern consumer machines are, by definition, the ones with the thinnest metal and/or shortest life pumps, etc.
The thickness is merely a comparison between different parts of the receiver, not an absolute value if using cheaper instruments.
A failed tank can just be devastating to the surrounding area. Most who post about catastrophic failures have got away with their mishap. Some have been reported where the user was not so lucky.
Catastrophic failures are not common - only occur once (per tank). That once is more than enough - for every user that has experienced one - to be much more vigilant going forward.
They can be “buy cheap, buy only once”. Industrial receivers are regularly tested for good reason. Insurance being the over-arching reason for safety.

Seeing the pressure stay the same or even drop as you pump is a good indication of what is about to happen...
I used to test one off tanks for certification many years ago, seen that happen a few times.

There's always the option of just using the good half by only half filling it
.I've never seen a failed tank myself. When I worked on hgvs I regularly changed tanks that had rusted through under the mounting straps and you could poke your finger through them.All these tools/instruments are useful but not definitive tests for safety.
