    can you please point me to them? so I can compare our research?

    in a private message faceless indicated the AD/DL article on oxygen sensors.
    it is clear that the research and recommendation in my article are in no way related to that article

    paul.... who absolutely does not like even the slightest feeling of hints beiing given that he would copy/paste from the internet in my articles, without mentioning the sources...


    ... makes me think of collateral damage....

    like it started a week ago on a french forum: some french instructor simply posts as a 'fact' that he found out that the rEvo has never been CE approved, that there has never been third party testing, that it was just the owner of the company who estimated that the unit coplied with the standard and so just put the CE stamp on it himself...
    that was taken over by another forum, and the 'kwakkel' started to spread...
    until we showed proof again etc, but than the poster all of a sudden 'was not sure on the CE approval of the rEvo....'

    I do not want to, because it's current policy on RBW I have to adhere.
    I may not like it, but I have to comply with law set on this board.
    For the same reasons I can't publicly discuss anything related to electronics area I'm currently interested in: DASH7 protocol implementation based on developing platform EZ430 Chronos.
    I prefer stay nobody and pursue my own private project goals.
    Moreover, Paul already spoke on my behalf, I'd prefer to stay silent, rather that being drawn in into yet another mud fight.

    Hi Paul,

    Great report, thanks for taking the time to create it.

    Can you say where the batch data comes from as I'd like to study that aspect a little more if possible.

    Thanks
    Matt.

    There is no such policy here about identifying yourself. Only posting on the apoc.

    So feel free to tell us who you are, Andrey.......

    Something a lot of people on here would have a very keen interest in, assuming you're looking to apply it to CCR diving?

    Hi Paul,

    I read the article but still have a question:

    (electronics is not my field)

    If the temperature compensation due to the NTU is perfect when the cell is new, what is the effect of the galvanic cell getting older, will the compensation become less efficient?

    If so is it possible to test cells by looking at calibration and readings from different temperatures?

    Regards

    Mikkel

    in general, without going into chemical/electronical detail: no

    the compensation adresses output variation due to temparature changes, and not to aging

    relative output variation due to temparature changes are different from output variation due to aging
