Long-lasting Buried CuSO? Reference Electrode is a commonly used device in pipeline cathodic protection systems, designed to monitor the potential of reinforced concrete structures and ensure they remain under effective cathodic protection. Below is relevant information:

Long-lasting Buried CuSO? Reference Electrode

Working Principle: Provides a stable reference potential through a saturated CuSO? solution, forming a potential difference with the structure under test to measure its potential.

Features: Excellent potential stability, long service life (up to 5–10 years), suitable for long-term monitoring.

Structure: Typically consists of a ceramic container, CuSO? crystals, a copper rod, and electrolyte.

Dedicated for Pipeline Cathodic Protection

Application Scenarios: Primarily used for measuring cathodic protection potential of buried pipelines, storage tanks, and other metal structures.

Function: Monitors pipeline potential, evaluates the effectiveness of the cathodic protection system, and ensures pipelines are protected from corrosion.

Monitoring Reinforced Concrete Potential

Method: The reference electrode is buried near the reinforced concrete structure, and the potential difference is measured to assess the protection status of the reinforcement.

Importance: Detects potential abnormalities in a timely manner, enabling measures to prevent reinforcement corrosion and extend the structure's service life.
