  • 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
    Filed: October 3, 2013
    Date of Patent: December 2, 2014
    Assignee: Hach Company
    Inventors: John Robert Woodward, Pierre Antione Robert Livrozet, Jean-Francois Maurice Rene Schvan, Russell Martin Young, Kevin James West

  • Unitary ionic probe
    Patent number: 8398835
    Abstract: A unitary ionic probe is provided. The unitary ionic probe includes a substantially elongate body including a central axis (AA), a proximal end, and a distal end. The unitary ionic probe further includes an active ion sensitive region that is located on and bonded into an exterior of the elongate body in a region of the proximal end and an active electrode in ionic communication with the active ion sensitive region. The unitary ionic probe further includes a reference ion sensitive region that is located on and bonded into the exterior of the elongate body and is spaced-apart from the active ion sensitive region and a reference electrode in ionic communication with the reference ion sensitive region.
