Comb. Au ring electrode

Comb. Au ring electrode
Order number: 6.0452.100

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

  • for titrations using Hg(NO3)2
  • for titrations in presence of chromium or iron

This electrode is stored in deion. water.
