Nitrate Ion-Selective Electrode BNC

Nitrate Ion-Selective Electrode BNC


Nitrate Ion-Selective Electrode BNC


Connect the Nitrate Ion-Selective Electrode BNC to our electrode amplifiers to measure the potential (mV) and calculate the concentration of nitrate (NO3) ions in aqueous samples.


The Vernier Nitrate Ion-Selective Electrode BNC Connector is a BNC-terminated electrode used to measure the concentration of nitrate (NO3) ions in aqueous samples. Use with Vernier interfaces requires the Electrode Amplifier. Also compatible with Go Direct® Electrode Amplifier and Go Direct® Ion-Selective Electrode Amplifier.


  • Range (mV):
  • Range (concentration): 1 to 14,000 mg/L (or ppm)
  • Reproducibility (precision): ±30mV
  • Interfering ions: ClO4, I, ClO3, F
  • pH range: 2.5–11 (no pH compensation)
  • Temperature range: 0–40°C (no temperature compensation)
  • Electrode slope: +55 ±3 mV/decade at 25°C
  • Electrode resistance: 0.1 to 5 MΩ
  • Minimum sample size: must be submerged 2.8 cm (1.1 in)
