We manufacture three different types of seawater reference electrodes for permanent installation to monitor steel potentials. We also manufacture a portable LD200W weighted seawater reference electrode for visiting on-site surveys.
Please take you pick from the selection below to find your required reference electrode.
Data sheets for the individual electrodes can be found in the panel on the right of this page.
Silver/silver chloride
Typical 1.2g silver per electrodeIn seawater the cells assume a potential which is dependent on the chloride ion concentration.
less 3mV in 24 hours.
80 mm long x 10mm diameter nylon barrel
White Nylon Barrel
White Nylon Inserts
Raychem cable product code 44A0111-16-6
More than 30 years at a leakage current of 1µA will result in the loss of 0.7 grams of silver. The functional life of the electrode will most likely to be determined by the life of the associated cables.
Siver/silver chloride Typical 1.2g silver per electrode
In seawater the cells assume a potential which is dependent on the chloride ion concentration.
less 3mV in 24 hours.
85 mm long x 15mm diameter nylon barrel
