BACKGROUND
In order to minimize corrosion of boiler hardware, the pH of feedwater must be controlled within a narrow range. Too low a pH will result in excessive corrosion of iron components, while too high a pH will result in attack on copper containing parts. Because boiler feedwater also must be very pure, a number of unusual problems can arise in measuring its pH. These include problems associated with (1) the liquid junction of conventional (flowing-junction) referenced electrodes, (2) the high resistance of the water, and (3) the unbuffered nature of the water.
