Mercury/Mercury Oxide Reference Electrode

Mercury/Mercury Oxide Reference Electrode (Hg/HgO), a reference electrode based on the reaction between elemental Mercury and Mercury Oxide. Filled with potassium hydroxide (20% w/w). Electrode potential is 98 mV vs. Normal Hydrogen Electrode (NHE)

• Laboratory grade PTFE/PP plastic shaft
• Porous junction tip is made with electroporous plastic
• Reference electrode body length is 14 cm
• Main body diameter is 15 mm, and is 8 mm at the glass junction
• Cable connection is 4 mm banana plug
• Includes Safety Data Sheet and black protective cover for junction tip

*Note: The fill solution is potassium hydroxide
