    Please forward to mgranot@hotmail.com the instruction manual and directions for calibrating the probe for a standard buffer solution. What is the correlation between the pH of the solution and the voltage output - is it linear? The probe and circuitry are what I need - but I lack the requested data to integrate the probe into the system. Your expeditious response would be most appreciated.

    Everthing is working fine. Instructions in the box are in Chinese. But they provided voltage and resistance tables, which can be read easily.
