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. Large
copper sulfate reservoir cuts refills to a minimum. Popular lengths are those shown.
Standard electrode is 8", but any length is available upon special order. |
