Borin Stelth 2

The Borin STELTH® 2 is a solid-state reference electrode designed for permanent installation in cathodic protection systems. Thanks to its advanced solid-state sensing technology, the electrode provides a constant and stable reference potential without the use of a liquid electrolyte, eliminating issues such as maintenance, drying out, and leakage. This makes the STELTH® 2 particularly suitable for long-term monitoring of buried pipelines, storage tanks, and concrete structures.

The STELTH® 2 performs reliably in moist to moderately dry soils and remains stable under changing environmental conditions. Its robust construction ensures a long service life with minimal maintenance requirements, providing a reliable and cost-effective solution for ICCP installations.

Available reference systems:

• Cu/CuSO₄ – Standard reference for soil and aqueous environments
• Ag/AgCl – Suitable for applications with high chloride concentrations
• Zn – Version for specific reference requirements in demanding corrosion environments

Typical applications:
Permanent monitoring of buried pipelines, tank installations, concrete structures, and other critical cathodic protection points where long-term measurement stability is required.
