AccuRef 30 Copper/Copper Sulfate Permanent Electrode

All new M.C.Miller Accuref electrodes include a (batch) Calibration Certificate.

• Electrodes are buried directly with native soil backfill - no need for composite backfills. Note: These products are suitable for use in neutral soil having a chloride ion content <500 ppm. (AccuRef Silver/Silver Chloride electrodes are recommended for use in higher chloride ion content soils)
• Depressed electrolyte freezing temperature of -4°F (-20°C) allows electrodes to experience a deep frost without freezing and cracking.
• Design life of 30 years (please see "Important Notes" below)
• 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)

1. These products must be installed according to the installation instructions provided.
2. These products are not guaranteed to maintain their calibration in all soil environments and it is incumbent on the customer to test their soil for the presence of any potential chemical contaminants prior to installation of these products. The M. C. Miller Company has not tested these products with regard to the effects of specific (potential) chemical contaminants on their calibration.
3. These products are not designed for submersion applications.
