dPt ring electrode
Tilausnro: 6.00403.300

Digital, combined platinum ring electrode for OMNIS with fixed ground-joint 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


The fixed ground-joint diaphragm is insensitive to contamination. c(KCl) = 3 mol/ L is used as reference electrolyte and storage solution.
