Conductivity isoPod™ (Model EP357) An electrically isolated, compact signal conditioner for use with e-corder units, for continuous monitoring of solution Studies where continuous monitoring of solution electrical con- ductance/resistance is required - e.g. ion chromatography, flow injection analysis, or conductiometric titrations. This isoPod be used with most types of two-electrode conductivity cells, including: • ET915 Dip-In Conductivity Electrode • ET908 Flow-Thru Conductivity Electrode (for V8" OD tubing) • ET916 Flow-Thru Conductivity Electrode (for Vi6 OD tubing) Use with Chart software version 5.5.6, or later, on Windows XP The Conductivity isoPod measures the alternating current (AC) across a suitable conductivity cell by applying a square bipolar potential pulse across the pair electrodes that comprise the cell. A DC analog voltage signal, proportional to the conductance, is output. The isoPod automatically sets excitation amplitude and frequency to an optimal value for a given gain range. The specific conductivity of a solution is obtained by calibrating the conductivity cell. First measure the conductance of a solution of known value (e.g. 0.1 mol/L KCI) then use the Units Conversion feature of the Chart software to equate this signal to the known specific conductivity.
