The STAPERM™ permanent reference electrode is a long-life, highly stable electronic device for measuring the voltage potential of the structure to be cathodically protected or measured in the surrounding electrolyte. Available through a worldwide distribution network of GMC ELECTRICAL, Inc., STAPERM™ reference electrodes can be used in installations of fresh water, underground, salt water and saturated saline soil conditions. STAPERM™ provides the means of measuring accurately the effectiveness of cathodic protection systems on the following:

  • Inside Water Tanks
  • Freshwater Dock Structures
  • Buried and Submerged Pipelines
  • Underground Storage Tanks
  • Waste Treatment Facilities
  • Steel Sheet Pile Bulkheads
  • Steel H and Pipe Piles
  • Concrete-Encased Steel
    and Steel Re-Bar
  • Offshore Platforms
  • Offshore Drilling Rigs
  • Offshore Pipelines
  • Ships, Work Boats and Yachts
  • Undersea Habitats

STAPERM™ features a unique Chloride Ion Trap that prevents contamination of electrode electrolyte - enhancing the service life (copper-copper sulfate and zinc-zinc sulfate only).

A specially developed porous ceramic electrode that houses tubes and contact plugs eliminates drying-out problems to insure the contact resistance to earth, providing more reliable readings.

Our reference electrodes are color coded for ease of cell type determination - eliminating guesswork and errors.

Our advanced allows for ease of installation and a long electrode life. It is perfect for inaccessible locations.
