Features & Benefits:

• Electrodes have same dimensions, fittings and ceramic tips as standard RE-5 (or RE-5C) portable electrodes
• Zero leakage of half-cell filling solution (copper sulfate solution)
• Zero contamination of half-cell by electrolyte (soil) elements, such as chloride ions - electrode can be used in any soil electrolyte
• Electrodes come in two versions: Regular and Anti-freeze.
• "Regular" electrodes are shipped with tap water inside the Lexan tube enclosure.
• "Anti-freeze" electrodes are shipped with anti-freeze solution (not containing copper sulfate) inside the Lexan tube enclosure (M.C. Miller's "Clear Anti-Freeze" solution).
• Electrodes arrive 'ready to use' - no need to prepare chemicals, etc., in the field.
