Metrohm's Aquatrode is designed specifically for pH assessment of low conductivity waters, making it suitable for a variety of environmental applications
Measuring pH in low ionic strength media, such as acid rain, river and lake waters, has always posed problems.
These include lengthy times for pH equilibration (sometimes as long as five minutes), diaphragm blockage due to silver chloride leaching out of electrode, or the necessity to add a salt to the water in order to speed up response times (this can affect original pH). Metrohm has recently launched the Aquatrode, designed specifically for low conductivity waters.
The device has a unique sleeve diaphragm, which allows quick response yet virtually no leaching of electrolyte - ensuring that quick and accurate responses are yielded.
The Aquatrode has internal shielding to reduce noise which could otherwise threaten the stability of the signal from the electrode.
