pH electrodes for measurements in aqueous and non-aqueous media

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.

DG111-SC: For pH measurement and acid/base titration in aqueous media. With S7 screw cap and detachable cable. ARGENTHAL™ reference system.

DGi111-SC: Same as DG111-SC, with Plug & Play functionality.

DG113-SC: For pH measurement and titrations in non-aqueous media. With S7 screw cap and detachable cable. Ag/AgCl/LiCl reference system.

DGi113-SC: Same as DG113-SC, with Plug & Play functionality and ARGENTHAL™/LiCl reference system and improved chemical resistance.

DGi114-SC: For pH measurements and acid/base titrations in clogged and protein or sulfide containing samples. With Plug & Play functionality and ARGENTHAL™ reference system.

DG115-SC: For pH measurements and acid/base titrations in aqueous media. Suitable for use in polar solvents, e.g. titration with perchloric acid in acetic acid or with sodium methylate in methanol and other media with low ion concentration. With S7 screw cap and ARGENTHAL™ reference system.

DGi115-SC: Same as DG115-SC, with Plug & Play functionality.

DGi116-Solvent: Especially suitable for acid/base titrations that require fast response times in non-aqueous media, e.g. TAN/TBN determinations in oils, titrations with perchloric acid, cyclohexylamine and alcoholic HCl, alkalis or Na-Methylate. For determination of epoxy numbers, acid values and saponification numbers, also free fatty acids in polymers, oils/fats and resins. With Plug & Play functionality and ARGENTHAL™/LiCl reference system.

DGi117-Water: For pH measurement and acid/base titrations in aqueous solutions of low ion conductivity and low buffer capacity. With integrated Pt1000 temperature sensor. Suitable for measurements in rain-, surface- and drinking water. With Plug & Play functionality and ARGENTHAL™/LiCl reference system.
