HI-4001-40 Ammonia Filling Solution information

Hanna's extended description

The HI-4001-40 fill solution is a chloride ion-containing electrolyte that is required to provide a reference potential for the HI-4101 ammonia gas sensing Ion Selective Electrode (ISE). As ammonia diffuses through the gas permeable membrane, the thin film of electrolyte on the surface of the pH sensing glass undergoes a pH change. The change in pH of the filling solution is proportional to the concentration of ammonia gas in the solution.
