The Oakton WD2750241 Double-Junction Silver/Sulfide Ion-Selective Electrode (Glass) is a fast and accurate electrode that does not require an external reference application, whether the application involves end point determinations in potentiometric titrations or continuous monitoring of specific ions. The WD-27502-41 is easier to use than separate sensing and reference half-cell electrodes. This double-junction combination ion-selective electrode is convenient to use in places where two electrodes will not fit.

The WD-27502-41 is double-junction in design, with a glass body that provides high-quality measurements for laboratory applications. Its improved glass seal enhances performance and reliability. Sealed inner junctions and refillable outer junctions accommodate special reference fill solutions, which is ideal for low-concentration measurements. Use the WD-27502-41 electrode with a meter that has a resolution of 0.1 mV for the most accurate results.
