Abstract: A controller for a pH probe that has a first interface for controlling a pH probe. Controlling the pH probe includes adjusting pH sampling. A second interface of the controller for pH probe is for controlling a source of vibration of the pH probe. The controller for a pH probe also includes a processor coordinating operation of the source of vibration and the pH probe. The processor is adapted to control, via the second interface, at least one of the following: when the source of vibration is activated relative to when a sample of pH is taken by the pH probe; vibration amplitude; vibration duration; or delay between vibration.
