Zinc Reference Electrodes

Zinc Reference Electrodes

MATCOR underground zinc reference electrodes are permanent CP monitoring cells for underground applications, offering the longest life of any permanent reference electrode type. Each uses high-purity zinc for a consistent −1.1V conversion factor to CuSO4.

Zinc Reference Electrodes Key Benefits

Longest lifespan among permanent reference electrodes
High-purity zinc for consistent quality
Constant -1.1V conversion factor to CuSO4
Stable, reliable readings from moisture-retaining backfill
Adaptable to various underground CP applications

Zinc Reference Electrodes Specifications

We use hi-pure zinc to assure consistent quality and a constant conversion factor of -1.1v to CuSO4. MATCOR zinc reference electrodes are suitable for underground cathodic protection applications:

  • Packaged in prepared backfill to maintain stability.
  • Size: 10-inch diameter x 24 inches long
  • Weight: 25 pounds
  • Model code: PRC-ZN-UG

An ACCA survey evaluates buried pipeline coating condition by measuring how an applied AC signal attenuates along the line. Sound coating holds the signal; damaged coating bleeds it into the soil. The rate of attenuation qualitatively ranks coating quality by segment and flags the areas with the most significant holidays.
Alternating Current Voltage Gradient (ACVG) surveys pinpoint buried pipeline coating defects and holidays, helping operator teams evaluate pipeline integrity and protect critical underground infrastructure.
Cathodic protection testing must be performed on a regular basis to maintain regulatory compliance and ensure continued corrosion protection of your assets. MATCOR conducts annual CP surveys that go beyond checking a box—our technicians collect the data, and our corrosion engineers interpret it and act on it.
An atmospheric corrosion survey evaluates whether airborne elements — such as sea salt, corrosive chemical plant discharge, or dust — are contributing to a structure’s corrosion. MATCOR technicians inspect the structure, test air and surface deposit samples, and deliver a full report with findings and recommendations.
