Feature overview

Combined silver ring electrode with fixed ground-joint diaphragm.
This electrode is suitable for precipitation titrations when the pH value varies (titrant silver nitrate) of, e.g.:
 

  • Chloride, bromide, iodide
  • Sulfides
  • Hydrogen sulfide
  • Mercaptans
  • Cyanides

 

The fixed ground-joint diaphragm is insensitive to contamination and the permanently fused-in silver ring is resistant to more highly concentrated acids and saline solutions.

c(KNO3) = 1 mol/L is used as reference electrolyte and storage solution.

Depending on the application, we recommend using an Ag ring electrode with a coating (AgBr, AgCl or Ag2S coating), which can be ordered accordingly.
