Ecotrode Plus means precision potentiometric measurements in low ionic strength samples

The continually increasing success of our Unitrode and Aquatrode Plus in pH measurement shows that the fixed ground joint is the more universal type of diaphragm.

It is largely insensitive to contaminants and requires only minimal maintenance. The fixed ground-joint diaphragm is suitable for a wide range of samples, from clear, ion-deficient solutions up to highly
concentrated suspensions or emulsions.

Its greatest strength, however, is its precision: The fixed ground-joint diaphragm allows low-noise potential measurements that are only dependent on the ionic strength and stirring speed to a minimal extent, thus meeting crucial requirements for a rapid and precise titration.
