Copper Sulfate Dependable Reference Electrode

Dependable reference electrodes for measuring pipe-to-soil (or water) potentials. Rugged laminated Bakelite construction withstands roughest field usage. Porous plug is made from selected birch, covered with rubber cap when not in use. Larger copper sulfate reservoir cuts refills to a minimum. Standard electrode is 8", but any length is available upon special order.
