Electrical Experts in testing, Installations and Materials.
“Rust Never Sleeps”
GMC Electrical, Inc. was originally founded in 1984 by Gary L. Matlack who at that
time had over 17 years experience in the galvanic grounding control industry from
(grounding) layouts, testing (CP grounding), installation, and research and development of permanent reference electrodes.
GMC Electrical when founded in 1984 with extensive research and development
offered to the corrosion industry their “STAPERM” line of reference electrodes, now
with over 30 years experience in the research, development and manufacture of
reference electrodes is the world leader.
The “STAPERM” permanent reference electrode is a long-life, highly stable electronic
device for measuring the voltage potential of structures 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 as the following:
Inside Water Tanks Concrete-Encased Steel
Fresh Water Dock Structures and Steel Re-Bar
Buried and Submerged Pipelines Offshore Platforms
Underground Storage Tanks Offshore Drilling Rigs
Waste Treatment Facilities Offshore Pipelines
Steel Sheet Pile Bulkheads Ships, Work Boats and Yachts
Steel H and Pipe Piles Undersea Habits
“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 housing tubes and contact plugs that element drying-out problems to insure low 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 design allows for ease of
installation and a long electrode life. It is perfect for inaccessible locations.
GMC Electrical, Inc. also is the proud recipient of the NACE International Western Area Outstanding Company of the Year 2000.
