The Aquatrode plus with plug-in head U from Metrohm was specially developed for measurements and titrations in low-ion and poorly buffered samples, such as surface waters and deionised water. These are the major benefits: special membrane glass with low resistance for measurement in low-ion solutions.This guarantees very short response times even in such difficult samples (fast measurement or end point titration); fixed ground-joint diaphragm with low resistance and very low, clearly defined electrolyte flow for fast, very accurate and reproducible pH measurement / titration; doublejunction design with maintenance-free inner electrolyte (gel) enables the bridge electrolyte to be adapted to the measurement conditions; and screening of the inner tube prevents interference due to static electricity.

In addition to these advantages, the Aquatrode plus now offers easy storage/fast electrode replacement/complete flexibility due to its removable cable.
