· These electrodes are buried directly with native soil backfill – no need for composite backfills. These products are suitable for use in neutral soil having a chloride ion content <500ppm. (AccuRef Silver/Silver Chloride electrodes are recommended for use in higher chloride ion content soils.)
· Depressed electrolyte freezing temperature of -20°C allows electrodes to experience a deep frost without freezing and cracking.
· Large electrical contact area (electrically active surface area) having hygroscopic characteristics promotes good electrode-to-soil electrical contact. (Note: Soil moisture content is a requirement for a buried metallic structure potential reading versus any permanently installed reference electrode, which means that readings in ultra-dry soil are not possible.)
Features:
· Electrode: Permanent Copper/CopperSulfate
· Applications: Direct burial in soil, assuming low (<500ppm) levels of chloride ion contamination.
· Low Freezing Point: -20°C.
· Design Life: 30 years.
· High Purity: CuCuSO4 and triple de-ionized H20.
· Cost: Less expensive than most Copper Sulfate permanent electrodes.
· Tip: Moisture absorbent ceramic tip.
· Evaporation: Will not dry out in low humidity and/or high heat.
· Wire: 25 feet of AWG 12 lead wire; cross-linked Polyethylene jacket, direct burial, low leakage, 600V, 90°C. 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).
