Portable Reference Electrode
Portable copper sulfate reference electrodes (CSE) are used for measuring potentials of underground structures and also for those exposed to fresh water. Their placement in close proximity to protected structures permits readings which are more exact. The tubing houses a 99.99% pure copper element and a supersaturated solution of copper sulfate.
Ag/AgCl reference cell is designed to obtain potential readings on structures located in brackish or salt waters. The cell is made from a silver element, which is contained in an inert tube and surrounded by a supersaturated gel of silver chloride on structures located in aqueous environments containing high chloride concentrations, such as salt water, reference cell has the proven electrical stability for long-life performance. Silver-silver chloride (Ag-AgCI) reference electrodes are used for potential measurements of tank internal and also in concrete structures.
