AccuRef 30 Copper/Copper Sulfate Permanent Reference Electrode with Integrated Coupon
All new M. C. Miller Accuref electrodes include a (batch) Calibration Certificate.
M. C. Miller's commitment to research and development of new technologies has led to the AccuRef 30. Due to the development of a unique electrolyte, these new electrodes have a projected lifetime of 30 years while maintaining the accuracy you have come to depend on.
Features & Benefits
- Electrode: Permanent Copper/Copper Sulfate.
- Applications: Direct burial in soil, assuming low (<500 ppm) levels of chloride ion contamination. Note: For applications in chloride ion contaminated soil, we recommend AccuRef Silver/Silver Chloride electrodes.
- Low Freezing Point: -4 °F (-20 °C).
- Design Life: 30 years.
- High Purity Materials: Copper rod & Copper Sulfate crystals.
- 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 (7.62 m) of #12 AWG XLPE RHW-2 lead wire; cross-linked Polyethylene jacket, direct burial, low leakage, 600 V, 194 °F (90 °C) Rating. Longer lengths of wire are available.
- Electrical Contact Surface Area: Approximately 16.4in2 (105.8 cm2) (a cylindrical surface, 1.5 inches in diameter and 3.5 inches in length)
