Smile DIY O2 Analyser
We've had the very one for nearly 12 months, easy to assemble (my bro-in-law tells me) and very accurate it would seem, we've X referenced it every time we get a fill with the gas suppliers kit and it's more than 0.2 within theirs so it's unclear who's is the more accurate.
It's a cheap solution & the guy gets good feedback.
We've mounted ours in foam inside one of those little waterproof boxes you can buy at dive shops and it's travelled the world with us with no issues.

Seemed to be a few years ago everyone built their own, now these days they are pretty cheap and not worth the bother. 35quid plus the sensor, so 80 quid, a ready built one doesn't cost much more.

MM

ps. Good to see the chap does admit to nicking the original idea from the OxyHackers Handbook - a very good read if I may say so.

pps. ok so it is quite a lot cheaper than ready made. Anyone reverse engineered one for a parts list, just nick the assembly instruction of the ebay site.

i built one. easy enough to do and i'm no soldering expert! always within a few tenths of other analysers so no problems with accuracy. the instructions are good and the seller is great.

and it makes an oxygen analyser a bit less of a 'black box'!

Have a look at the El-Cheapo at Oxycheq too.

There may be customs costs etc to add but at $100 including the sensor it might be worth it.........this Ebay one looks remarkably similar

There's an O2 analyser you can buy for £85 complete with sensor and all finished. Have a search on the boards and it'll come up. Not worth building your own.

Do a search for "oxygen".
