These liquid membrane electrodes are available as single half-cells or as combination electrodes complete with reference electrode.

• Easily replaceable membrane modules
• Combination electrodes provide the same selectivity and response as the half-cells, but include superior double junction reference
• Combination electrode is ideal for field measurements

The sensing surfaces of these electrodes are comprised of a homogeneous polymer matrix containing organic ion-exchangers selective for the determined ion. They are available for measurements of nitrate, potassium and calcium.
