The YSI 6884 nitrate ISE sensor consists of a silver/silver chloride wire electrode in a custom filling solution. The internal solution is separated from the sample medium by a polymer membrane, which selectively interacts with nitrate ions.

When the probe is immersed in water, a potential is established across the membrane that depends on the relative amounts of nitrate in the sample and the internal filling solution. This potential is read relative to the Ag/AgCl reference electrode of the sonde pH probe. As for all ISEs, the linear relationship between the logarithm of the nitrate activity (or concentration in dilute solution) and the observed voltage, as predicted by the Nernst equation, is the basis for the determination.
  • Range: 0 to 200 mg/L-N
  • Resolution: 0.001 to 1 mg/L-N (range dependent)
  • Accuracy: +/-10% of reading or 2 mg/L, whichever is greater
  • Warranty: 6 months
