Calomel Standard reference electrode (saturated KCl) (013458)

SCE (Saturated Calomel Electrode) has been used as reference electrode instead of SHE (Standard Hydrogen Electrode) for the reference potential measurement of electrodes in electrochemical research.


Reference potential
Hg2Cl2 + 2e = 2Hg + 2Cl-
E0=241 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

∗Keep the reference electrode in a cold dark place.
