Ion-selective Electrodes

The 500 Series half cells The 800 Series combination electrodes Electrode types: Ammonia ( NH4+ ) Lead ( Pb2+ ) Bromide ( Br– ) Cadmium ( Cd2+ ) Calcium ( Ca2+ ) Chloride ( Cl– ) Cyanide ( CN– ) Fluoride ( F– ) Iodide ( I– ) Potassium ( K+ ) Copper ( Cu2+ ) Sodium ( Na+ ) Nitrate ( NO3– ) Silver ( Ag+ ) Sulfide ( S2– ) WTW offers a complete range of ion-selective electrodes for challenging ISE applications. Choose between two types: the 500 Series half cells, which require a separate reference electrode, or the 800 Series combination electrodes. These combination electrodes with built-in reference are easy-touse, and offer the option of measuring in small volume samples. Plus, they have an out-standing price performance ratio.
