Ionselective Electrodes, METTLER TOLEDO

Ion-selective/gas-sensitive electrodes are used to determine the concentration of individual ions and gases in aqueous solution. Their easy operation and comparatively simple construction often provide advantages over elaborate wet-chemical, instrument-based analysis methods.

Ion-selective electrodes have to be combined with a suitable reference electrode (InLab® 302). The latter is not required by gas-sensitive eletrodes (combination electrodes).
