Figure 1. Principle of a two-point calibration of a pH electrode system, at pH 6.00 and 8.00. (a) Signal before calibration (dotted line); (b) Calibration at pH 6 at electronic zero (0 mV), using the zero adjustment (+; additive as shown by the downwards arrows of equal length); (c) calibration of gain setting (slope) at pH 8, observing the οpH of 2.0 units (x; multiplicative or proportional, as shown by the constant position of the 0 mV signal); (d) The full line of correspondence is obtained by shifting the entire curve to the correct absolute pH value (+, additive).
