Electrodes An AmmoLyt
®Plus
700 IQ sensor ready to measure requires a
reference electrode and an ion sensitive electrode for the main
parameter, ammonium. The electrodes are screwed into the electrode
support. The electrode support has two receptacles for this.
Automatic potassium
compensation
With the aid of the automatic potassium compensation, the influence of
potassium ions on ammonium measurement due to measuring
technique is compensated for during measurement. To determine the
potassium concentration, the AmmoLyt
®Plus
700 IQ is equipped with a
potassium electrode for compensation.
