    old oxygen cell recycling

    Is there a use for old oxygen cells?
    Do we simply have to throw them away?
    If yes what is the best way to throw away old oxygen cells without polluting environment?

    thanks

    Recycle as they would be old batteries.

    thanks for the info, so no second life? alternative use for scientific instruments or anything like this?
    thanks

    I know of a few people that use them in their oxygen analyzers, figuring as long as they can still read 100%...

    YMMV.

    analyzers is about the only thing you can do with them. Once the galvanic compound is depleted there really isn't anything you can do with them

    Duh (sound of hand slapping forehead) why did that never occur to me? I really hated buying new cells for my analyzer (which I use very infrequently). I bet you could get half a useful year out of a "not safe for depth" cell.

    You can do plenty of other things with them. Make Christmas ornaments, use them as misshapen golf balls, throw them at people you don't like...the possibilities are endless.

    The only USEFUL thing is to put in an analyzer. Analox rates their sensor for 4-5 years in air (as an example), so your 6 month old sensor will be just fine.

    they last quite a bit longer than 6 months when they come out of the breather

    Which oxygen analysers can take a Vandagraph type cell with a molex connector?

    Cool Re: old oxygen cell recycling

    I was thinking of using one of these:


    https://www.ebay.com/itm/DC-Millivol...-/170751371122


    and then wiring in a molex connector. Just use a calculator to determine the %O2 based on the reading when calibrating and the response gain slope. Instant O2 meter for $11 (if it actually arrives from China)..


    Here is one that is presumably in the US: https://www.ebay.com/itm/US-Stock-DC...rd!24060!US!-1



    I haven't tried that particular meter so let me know how it turns out if you build one...
