[-edit-] > how it's done in the real world... Is parial pressure mixing a good thing? My local shop always uses an analyser for Nitrox (and trimix, I guess) mixes. The chap who does the mixing (currently) starts with an empty bottle and he knows that for a final mix of X% O2, he needs to start with Y bar of pure O2, then top it up to final pressure with air, then analyse and cut back by emptying a little out of the bottle and topping up with air and testing again. I've watched him do this fairly often - He deliberately adds a little too much O2 so he can cut back to the exact final mix (No O2 booster yet, but he's working on it!) His meter is accurate to 0.1% - I don't think that you could get that accurate by partial pressure mixing - Or can you? Does anyone do it this way and consistently get accurate results?
