Interesting one this, has anyone other than me ever tested it? I out of interest put an analyser on a tank of balloon gas, 0% O2. So don't rely on it having any oxygen in it.

No M8 never tested it, and what I posted could be a load of bollocks, (why change the habits of a lifetime) it may simply be an urban myth.

You would think so, sensibly, but I beg to differ.
I got one of those disposable Helium party gas cylinders from Makro to do my kids party and out of curiosity plonked it on my O2 sensor - and it read, er, 0%.

Would seem to much hassle to have specific Helium/O2 cylinders for "idiot friendly" users, Ive seen some places with the J and it looks like normal helium to me (by that I mean the markings), if it had 16% could side sling it for a huge Heliox gas reserve!
