013694 : Reference electrode for alkaline solution
The RE-61AP reference electrode is made of Hg/HgO instead of calomel paste, and 1 M sodium hydroxide is used as an electrolyte solution. It is used under high pH environment as reference electrode. Also, potassium hydroxide solution can be used as a internal solution, instead of sodium hydroxide solution.
Reference potential |
HgO + H2O + 2e = Hg + 2OH- E0=118 mV vs RHE (25 deg C) ∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013597). |
The electrode holder is delivered empty, to be filled with 1 M NaOH aqueous solutions by the user. Please pay attention to handling. ∗1 M NaOH solution used in this electrode is not provided, also we do not supply.
Holder material: Polymethylpentene, for the high chemical resistance is used.
Main body: Screw type to be removable
Liquid junction: Ceramic tip
∗Keep the reference electrode in a cold dark place.
