    The rebreather World Store stands behind the products we sell. We are aware of this situation and are looking at how best to handle it. I will have a more formal statement shortly. However, do not hesitate to contact me directly with any questions you may have.

    Re: Attention!!! AI O2 Sensor Recall

    I just spoke to Mark Gregus at AII to talk about this - apparantly there was a manufacturing issue with the last few batches that caused some sensors to fail early, he said that this does not affect every sensor but they are replacing all recent orders to their resellers in the next few days.

    The affected AII sensor codes are:

    PSR 11-39-MD
    PSR 11-39-APD
    PSR 11-39-JD

    So if you have bought a recent AII sensor - then even if it appears ok - my advice woud be not to dive it and get it replaced from your reseller.

I only 'like' to take shot at idiots - of which there are many and of which Martin certainly isnt one. If you regard being independantly ojective about and sensitive to all units safety issues and voicing critisism of what i see as poor design in any system as 'taking a shot' then well Im happy to be guilty as charged.
    takes the trouble of testing each R22 cell he receives before re-selling them....
    i aplaud anyone or anything that makes our dives safer.

    Maybe a tip for the RBW shop? just buy some of those new shiny Narked@90 cell-checkers and test'm all before distribution. Raise the price a bit, as surely one's life is worth a few dollars/euros/pounds every 6 or 18 months (depending on which school of change regime you're in).
    You could even make two lines: one cheapo, for the dollar-saving fools, saying "not tested, just resold", and one with a premium, saying "testing for 4 ours at 2.0 bar PO2 and was o.k.".
    i was going to ask how APD tests them is that how they test them or is that narked@90s way?

    Hi Stuart,

    Perhaps RBW could set up a 'manufactures notice forum' where recall notices, product warnings, mnf suggestions etc could be posted (by them) in order to reach majority of their customers as quickly as possible with safety info

    Re: Attention!!! O2 Sensor Recall

    Mike,

    o.k., I'll gladly take your word on it, and will apologize If I got that wrong. You come on over rather strong however lately though... I thought I had the "privilege" over here at being the ultimate blunt one....

    As to test-protocol: don't know; ask Martin for details. It is just what I made up on the fly as seeming sensibie: some prolonged duration (at least a few hours), and a high PO2 (at least way above the operational high SP). Mind you, given the very nature of these cells, there is no such thing as a "perfect" test - other than leaving them in a testkit for six months or so.... However, from what I have gathered on experience over the last 10 years, many (but admittedly not all) will show up in the first few hours of use. Reading through this AI thread, most in these faulty badges do as well. So it at least would add to raising the probability of it being o.k. considerably - but never to 100%.
    Other than that: always structurally mistrust what's hanging off your shoulders. Trust is good, control is better. So keep those 6 meter O2 flushes & incidental O2 squirts at depth in for checking current limitation...

    ciao,

    Tino.

    Great Idea Mike,

    I will get that setup and also set it to appear at the top of the front page if a manufacturer posts in it.

    Your prob quite right. The one that failed in Song Hong was a new one I put in the BOB the night before. I soaked it overnight in a sealed bag of pure O2 to ensure the cell had fully 'woken up' and it apeared fine, but it died very quickly in ppo2 of 1.1bar after about 3 hours use next day. I suspect a thorough test would include temp as well as ppo2 and time - But who knows

    it might be nice if having it encourages mnf to also post their suggestions on how best to use, maintain or check their products. Im sure mnf often have knowledge, little tricks of the trade if you like, that we could benefit from. currently they have no official direct notice facility and word only filters down through users - this could be a better way i think,

    Just thinking this through - I am guessing if a product has its own forum then the appropriate place would be there to post though for general tips and tricks that could then be made sticky? Although I guess they could post any where and the staff team coudl move as appropriate.

    Re: Attention!!! AI O2 Sensor Recall

    The trouble with having cells individually tested by a reseller is that it requires the package to be broken, and therefore no longer stored in an inert atmosphere unless the resellers can set this up. The shelf life is therefore reduced, which may be an issue for "spare" cells.
    What we really need is cells that are all individually tested by the manufacturer prior to sealing/sale. I'm assuming this doesn't happen already. Personally I would pay a premium for such cells.
