    Can you give us a link to your pH sensor. What is your project about besides implementing a pH sensor?

    If it's a calomel electrode, the output is 59.2 mv/pH unit. You just need a high impedance amplifier to buffer the electrode output.

    I for one am extremely impressed with the "very very urgent" nature of your original request.

    IP suggests they are located in Palestine, possibly Essen. Perhaps "urgent" is a translation error of some kind. Did they really mean عاجل

    Can I draw the OPs attention to this. Without any proper input this topic is going nowhere.

    Sorry to drift off topic but what does the abbreviation 'OP' stand for, original poster? I've seen it here a few times but never could find the meaning. Thanks

    Either "opening post(er)" or "original post(er)" dependant on context.
