• Minimum 20-year service life.
• Available in three models: Cu-CuSO4, Ag-AGCl, Zn-ZnSO4.
• Color coded for quick and easy identification.
• Special porous ceramic contact plugs allow removal and re-entry into liquid without damaging the electrode. The unit is thus reusable and may be reactivated (after use) for a period of up to one year.
• Technologically advanced "ion trap" prevents contamination of Cu-CuSO₄ electrolyte.
• High-impact resistant plastic electrode case will not deteriorate even in highly corrosive environments.
• Complete installation instructions included.
