Abstract
A method is provided for measuring the impedance of a pH sensor electrode. The method includes applying a positive voltage pulse to the pH electrode and taking a plurality of samples of the sensor voltage response and, from those samples, estimating the impedance of the sensor electrode. Then, a negative voltage pulse width is dynamically adjusted to cancel out the induced charges from the positive voltage on the pH sensor so that the sensor quickly recovers to read subsequent media pH levels.
