pH-Electrodes

DG electrodes are used for pH measurement and titration in difficult samples, low ionic and non-aqueous media.

DM electrodes with silver and platinum rings are suitable for redox titration with and without pH change, e.g. argentometry and Karl Fischer titration.

Plug & Play capable electrodes are automatically recognised by METTLER-TOLEDO pH meters and electrode type, serial number, calibration data and operating hours can be read out and processed by the software.
