WE50-Salt - Silver/Silver Chloride Reference Electrode for measuring Anodes and Cathodic Protection.
Measuring the vessel's potential voltage underwater is critical to determining if the vessel's anodes are functioning correctly and ensuring the vessel is adequately protected.
To assess the adequacy of a vessel's cathodic protection, it is imperative to measure the potential difference between the metallic surfaces and water. This involves creating connections with both the structure and the electrolyte (water). This is achieved by measuring the potential difference (voltage) in the water with a high-precision reference electrode. The reference electrode creates a connection to the electrolyte.
When conducting potential measurements on the underwater metals, the WE50 Series is connected to a high-input impedance multimeter (minimum 10 MegOhm). The electrode is then immersed in the water from the vessel's side to reach predetermined water depths. Once the electrode is at the desired depth, the potential of the metals is measured by connecting the test lead from the meter to the various underwater metals and recording the voltage displayed on the multimeter.
