YSI Digital VARiON® Ammonium/Nitrate/Potassium/
Chloride for the IQ SensorNet System
t
The VARiON is a rugged, online probe for measuring Nitrate and
Ammonium concentrations with Ion Selective Electrodes (ISEs) in
wastewater process applications.
The VARiON probe is used within the IQ SensorNet system and
can therefore be networked with other probes and parameters
for a complete process monitoring and control system. It can
measure, report and control off of the ammonium and/or nitrate
measurements with automatic compensation for potassium (for
ammonium) or chloride (for nitrate).
Parameters:
Nitrate
Ammonium
The VARiON is the ideal probe for quantitative measurement of
nitrogen in a wastewater treatment plant. The efficient control of
Nitrogen in wastewater relies on the ability to take the measurements directly in the process. This direct ISE measuring technology is possible with the VARiON sensor, enabling optimization of
a plant in respect to process efficiency and energy consumption.
