Chloride Ion-Selective Electrode BNC

Connect the Chloride Ion-Selective Electrode BNC to our electrode amplifiers to measure the potential (mV) and calculate the concentration of chloride (Cl-) ions in aqueous samples.


The Vernier Chloride Ion-Selective Electrode BNC Connector is a BNC-terminated electrode used to measure the concentration of chloride (Cl) ions in aqueous samples. Use with Vernier interfaces requires the Electrode Amplifier. Also compatible with Go Direct® Electrode Amplifier.


  • Range (mV):
  • Range (concentration): 1 to 35,000 mg/L (or ppm)
  • Reproducibility (precision): ±30mV
  • Interfering ions: CN, Br, I, S2-, OH, NH3
  • pH range: 2–12 (no pH compensation)
  • Temperature range: 0–80°C (no temperature compensation)
  • Electrode slope: +56 ±3 mV/decade at 25°C
  • Electrode resistance: 1 to 5 MΩ
  • Minimum sample size: must be submerged 2.8 cm (1.1 in)
