Reference Electrodes

AccuRef 20 Permanently-Installed Copper Sulfate Reference Electrodes

Cat. #14630
Price $100.00

These electrodes represent state-of-the-art technology and are a result of MCM’s commitment to on-going research and development for the Cathodic Protection industry. The AccuRef Permanent Electrodes are designed for 40-year life expectancy, de-rated for engineering practices to 20 years.

Features:

pipeline surveys
  • Electrode: Permanent Copper/Copper Sulfate.
  • Applications: Direct burial in soil, assuming low (<500ppm)levels of chloride ion contamination. Accuref Silver/Silver Chloride electrodes are recommended for use in chloride ion contaminated soil.
  • Low Freezing Point: –20oC.
  • Design Life: 20 years (AccuRef 20).
  • High Purity: Cu/CuSO4 and triple de-ionized H2O.
  • Cost: Less expensive than most Copper Sulfate permanent electrodes.
  • Tip: Moisture absorbent ceramic tip.
  • Evaporation: Will not dry out at low humidity and/or high heat
  • Wire: 25 feet of AWG 12 lead wire; cross-linked Polyethylene jacket, direct burial, low leakage, 600 V, 90oC Rating, USE - 12/RHH/RHW-2. Longer lengths of wire are available.
  • Electrical Contact Surface Area: Approx. 16.4 square inches (a cylindrical surface, 1.5 inches in diameter and 3.5 inches in length).

Antifreeze is added to the solution to lower the freezing point to –20 degrees Centigrade. This enables the AccuRef Permanent Electrodes to survive a deep frost without freezing and cracking the electrode.

Boiling point is 100oC.

AccuRef 20 contains 80 grams of high purity Cu 99.99% and 500 Milliliters of saturated Cu/CuSO4.

Dimensions: 2.77” diameter, 15” long and 3.9 pounds.
