Katalogové číslo: 6.00450.100S

Combined silver ring electrode with fixed ground-joint diaphragm.
The permanently fused-in silver ring is resistant to more highly concentrated acids and saline solutions and is coated with sulfide (Ag2S) for increased sensitivity and a better limit of detection.
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.

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