    I constructed the high-impedance voltmeter based on the design you provided in Volume VI Experiments section of your site in allaboutcircuits.com. I am trying to determine the potential of an iron electrode dipped in electrolyte solutions as part of my corrosion measurement project. I would like to measure potentials in the range of -1000 mV to +10 mV.

    I am new in electronics and I would like to know if your design can make measurements in this potential range. If it cannot, I would gladly appreciate if you can make suggest modifications to the design.

    Thank you.
