Reference Electrodes for CP Monitoring
BSS Technologies supplies a comprehensive range of reference electrodes for cathodic protection monitoring. We offer stable reference cells calibrated to deliver precise structural potential tracking across soil, marine, and concrete environments.
What Are Reference Electrodes
Reference electrodes are critical diagnostic tools in corrosion control that provide a constant, highly reproducible electrical potential. Because their internal electrochemical makeup remains stable despite external environmental changes, this potential acts as a reliable baseline benchmark for all corrosion mitigation efforts.
Field engineers use this stable baseline to measure the true structure-to-electrolyte voltages of buried or submerged assets, such as pipelines and storage tanks. By measuring voltage differentials directly against this reference point, operators can accurately verify if an active cathodic protection (CP) system is delivering sufficient current to halt degradation and meet strict international standards.
Types of Reference Electrodes We Offer
To fulfil variable installation environments and survey scopes, BSS Technologies supplies specialized reference cells split into distinct operational types.
Portable Reference Electrodes
These lightweight elements are built for routine field diagnostics and step-over inspections. Encased in high-impact ABS tubes, they use liquid or gelation-filled chambers to maintain rapid contact with earth or electrolyte matrices during walk-over pipeline testing.
Permanent Reference Electrodes
Engineered for ultimate longevity, these units are buried permanently alongside buried pipeline routes or storage tank bottoms. We provide each sensor core inside a heavy-duty cotton bag prefilled with a non-polarizing clay backfill mix to absorb earth moisture and maintain low contact resistance over long decades.
Zinc Probe Reference Electrodes
Recognized for having the longest service life among permanent-type reference electrodes, these high-purity zinc units deliver stable and reliable corrosion potential measurements for both onshore and offshore applications. Built with a sturdy, highly conductive design that offers strong corrosion resistance, these probe-style electrodes are specifically engineered for simple installation and maintenance within internally protected steel water boxes, tanks, and piping systems.
