Test Station - Two Wire
- Built using an industry approved test station head and two leads wires
- Support tubing is ultraviolet protected and chemically resistant
- Assembled with two white underground rated test leads that are to be permanently attached onto the structure.
Installed directly above the underground pipe or tank, the two-wire test station can be used to take structure-to-soil potentials as well as an indicator of the structures location. Two white wires are included so you can attach them onto the structure as a primary and secondary connection in case of wire failure. To get the best indication of what is going on at the pipes level, a permanent copper-copper sulfate reference electrode should be installed at the time of backfilling. When attaching the wires to the pipe a thermal weld connection should be used and any exposed area of the pipe should be re-coated with an approved coating method by the pipelines owner.
When ordering a four-wire test station, please indicate the number of test stations required for the task. Standard lead length for the assembly is 5 meters (16 ft.) of wire, please indicate if additional lead length is required for more remote locations.
