3ft Cable BNC Connector


  • Glass Body Electrodes: ideally suited for most routine pH measurements for accuracy, high temperature, and ease of cleaning.
  • Calomel reference electrodes (Hg/Hg2Cl2) can give very accurate potentials. Both its reproducibility and potential stability are superior to those of the Ag/AgCl electrode, although only at a constant and relatively low temperature. Calomel is subject to a constant and relatively low temperature fluctuation with a temperature limitation of 80°C.
  • Double junction electrodes are less likely to become clogged
  • For situations containing proteins, sulphide, and TRIS, use double junction electrodes.
  • Refillable Reference Cell: selected for high accuracy, stability, and longer electrode life. Refillable types sacrifice convenience and ease of maintenance.
  • Sealed Reference Cell: sealed gel-filled reference electrodes are designed for convenience where minimal maintenance is required. Slightly lower accuracy and shorter life must be taken in account.
