RE-2BP Calomel Reference Electrode (SATURATED KCL)

Calomel Standard reference electrode (saturated KCl)

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.

RE-2BP Reference electrode
Reference potential
Hg2Cl2 + 2e = 2Hg + 2Cl-
E0=241 mV vs RHE (25 deg C)
∗ The reference potential is the measured value using rhek


  • Holder material: Polymethylpentene, for the high chemical resistance is used.
  • Liquid junction: Ceramic tip
