The RE-2CP Reference electrode is recommended, if you dislike a contamination with chloride ion from chloride type reference electrode.
| Reference potential |
| Hg2SO4 + 2e = 2Hg + SO42- E0=657 mV vs RHEK （25°C） ∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013373). |
- Holder material: Polymethylpentene, for the high chemical resistance is used.
- Liquid junction: Ceramic tip
| Catalog No. | Description | Eletrolyte | Purpose |
| 013459 | RE-2CP Reference electrode free from chloride ion (saturated K2SO4) | saturated K2SO4 | RE-2CP Reference electrode free from chloride ion |
∗Keep the reference electrode in a cold dark place.
