•Product Sheet: PUR-Sense™ Model 410VP Four-Electrode Conductivity Sensor
The Model 410VP four-electrode conductivity sensor is intended primarily for the determination of electrolytic conductivity in the pharmaceutical and food and beverage industries. Typical applications include monitoring the concentration of CIP solutions and rinses, monitoring eluents in chromatographic separations, and detecting liquid interfaces.
The Model 410VP sensor has a flat sensing face consisting of four circular electrodes arranged in a row. The analyzer injects an alternating current through the outer electrodes and measures the voltage across the inner electrodes. The conductance of the electrolyte solution between the voltage electrodes is readily calculated from the measured current and voltage. Because the voltage measuring circuit draws almost no current, errors caused by series capacitance and cable resistance, which are significant in two-electrode measurements at high conductivity, are greatly reduced. The Model 410VP sensor covers the range 1 uS/cm to 1400 mS/cm.
