SKU006884


Add YSI ISE sensors to complement any sampling regimen with chloride, nitrate and ammonia measurements. Designed to work hand-in-hand with YSI's pH sensors, ISEs provide nutrient data that can benefit your current sampling project.

This sensor must be installed into a 6-Series sonde to function. Does not function on its own.

  • Overview

    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.
