Combined redox 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.
DM140-SC: Combined platinum ring redox electrode. For titrations with a change of the pH value, e.g. oxidation with potassium permanganate, copper determination with iodine, back titration with thiosulfate. With S7 screw cap and ARGENTHALä reference system.

DMi240-SC: Same as DM140-SC, with Plug & Play functionality.

DM141-SC: Combined silver ring electrode for argentometric titrations, determination of halides, sulfides and mercaptanes in aqueous media. Also suitable for determination of salt and silver content. With S7 screw cap and ARGENTHALä reference system.

DMi141-SC: Same as DM141-SC, with Plug & Play functionality.

DM143-SC: Double pin platinum electrode for electrochemical titrations, e.g. water determination acc. to Karl Fischer, bromine number determination and sulfur dioxide determination in aqueous media. With S7 screw cap and ARGENTHALä reference system.

DMi144-SC: Combined platinum ring redox electrode. For titrations with a change of the pH value, especially designed for COD determination with the Rondo 20 COD rack. With Plug & Play functionality and ARGENTHALä reference system.

DMi145-SC: Combined silver ring electrode for argentometric titrations, determination of halides, sulfides and mercaptanes in aqueous media. Also suitable for determination of salt and silver content. With Plug & Play functionality and ARGENTHALä reference system.

DMi148-SC: Combined silver ring electrode for argentometric titrations without a change of the pH value. For determination of halides, cyanides, sulfides and mercaptanes in mineral oil and bioethanol.
