Your Perfect Partner for Ammonium and Nitrate Measurement
WTW - a xylem brand
Very Easy
The new matrix adjustment: Easier and faster than ever! Benefit from intuitive operation for simple adjustments.
Less Costs
Cross compensation: One electrode, several sensors. Compensate multiple sensors simultaneously, saving costs.
More Possible
Ammonium measurement in heavily polluted media: Measure high NH4-N concentrations (up to 2,000 mg/l) without chemicals.
Proven Quality
Leveraging over 15 years of experience in ion-selective on-line measurement, WTW offers sophisticated and reliable measurement techniques without compromises.
Applications include control of intermittent nitrification/denitrification, optimization/monitoring of simultaneous nitrification/denitrification, SBR process control, and measurement of high ammonium load in centrate and process water.
VARION® Plus
Multiparameter in situ probe with short response time, variably applicable. Ideal for fast measurement of Ammonium and Nitrate with dynamic compensation of potassium and/or chloride.

AmmoLyt® Plus
Single parameter in situ probe for the measuring of Ammonium with dynamic compensation of potassium.

Calibration and Electrodes
Calibration Free: WTW's ISE sensors measure directly in the process without chemicals or sample taking. Mature technology makes calibration with standard solutions obsolete, ensuring long-term stable measurement values.
Single Exchange of Electrodes: The single electrode principle ensures only the necessary component is replaced.
Robust Electrodes: WTW's robust ISE electrodes simplify handling and cleaning.
Direct Connection to the IQ Sensor Net
Benefit from connection of up to 20 sensors, measurement of all important parameters, and maximum communication possibilities.
