Borin SRE-007-CUY-NSW Reference Electrode

The Borin Stelth 2 SRE-007-CUY-NSW reference electrode is a copper–copper sulfate (Cu–CuSO4) reference electrode designed for direct burial in soil or concrete as part of cathodic protection (CP) systems. As a member of Borin’s Stelth 2 family, it uses Cu-CuSO4 chemistry to provide a stable reference potential in buried environments, with the SRE-007-CUY designation identifying the copper–sulfate configuration intended for buried-service installations. Industry references and installation literature confirm the SRE-007-CUY model as a buried-reference electrode used in CP projects, and supplier listings have shown variants with extended lead lengths—commonly around 50 ft, 66 ft, or 132 ft of wire for field CP measurements. Typical applications include CP monitoring and protection for buried pipelines, tanks, and other underground structures where a reliable reference is required.
