SILVER/SILVER CHLORIDE WE300 LOW IONREFERENCE ELECTRODE FOR USE IN POTABLE WATER
Application
Silvion silver/silver chloride reference electrodes have, since 1985, been recognised by many as the highest quality silver chloride electrodes available. Constructed using advanced techniques which result in a porous silver matrix around a wire skeleton they provide a significantly higher electrode surface area than traditional electrodes constructed of silver wire which enhances both life and stability.
Silvion WE300 reference electrodes are designed specifically for installation in potable water of very high resistivity. A pre-determined reduced chloride ion concentration (0.05M) around the element is maintained by using an inert electrolyte compatible with the silver/silver chloride element. Since the chloride concentration of the internal electrolyte is approximate to that of the outside electrolyte, leaching of the chloride ions and consequential variations in the reference electrode potential are eliminated.
