Abstract
The present invention pertains to an apparatus for evaluating the signal strength from the pH sensor to determine whether the sensor is hydrated sufficiently to accurately measure pH. This is accomplished by utilizing circuitry that periodically sends a low voltage signal to a suitable pH sensor and then receiving the resulting waveforms which are analyzed by a processing receiver. The electrical connection between a suitable pH sensor and hydration monitoring circuitry is generally hard wired. In one embodiment, a processing receiver is coupled with the hydration monitoring circuitry as a single apparatus. In a second embodiment, the processing receiver can be independent and located remote from the hydration monitoring circuitry. In this embodiment, the hydration monitoring circuitry and the processing receiver are electrically connected using either hard wired techniques or wireless technology. In addition, the processing receiver can include data recording capability.
