  • Ionic probe
    Patent number: 8900441
    Abstract: An ionic probe is provided according to the invention. The ionic probe includes an active electrode configured to generate a measurement signal for an external test fluid, a first reference electrode configured to generate a first reference signal, and an at least second reference electrode configured to generate at least a second reference signal. The measurement signal is compared to the first reference signal and the at least second reference signal in order to determine an ionic measurement of the external test fluid.
    Type: Grant

  • Differential pH probe
    Patent number: 8366895
    Abstract: A differential pH probe design uses a container having an outer surface and an inner volume, where the inner volume is divided into a first chamber and a second chamber. A first pH-sensitive area is located on the outer surface of the first chamber where the first pH-sensitive area is configured to be exposed to a sample. A second pH-sensitive area is located on the outer surface of the second chamber where the second pH-sensitive area is shielded from the sample and is exposed to a buffer solution. A first electrode is configured to detect a first voltage in the first chamber and a second electrode is configured to detect a second voltage in the second chamber. Circuitry is coupled to the first and second electrodes and configured to process the first voltage and the second voltage to determine a pH of the sample.
