    All pH electrodes rely on a principle known as the Nernst equation (above). The Nernst equation takes a voltage (mV) reading and correlates it to ion concentration (the pH). This correlation forms a straight line. For pH electrodes, the theoretical mV value at pH 7 is 0mV (neutral) and the slope of the line is 59.16mV.
