Typical 3g silver per electrode
In seawater the cells assume a potential which is dependent on the chloride ion concentration.
less 3mV in 24 hours.
115 mm long x 24mm
White nylon barrel and inserts with IP68 cable gland
More than 50 years at a leakage current of 1µA will result in the loss of 1.0 grams of silver. The functional life of the electrode will most likely to be determined by the life of the associated cables.
