Feature overview

Combined platinum ring electrode with a ceramic pin diaphragm.
This electrode is well suited for redox titrations when the pH value varies, e.g.:
 

  • oxygen content according to Winkler
  • determination of hydrogen peroxide with KMnO4
  • diazotization titrations


c(KCl) = 3 mol/L is used as reference electrolyte and storage solution.
