WTW VARiON Plus 700 IQ

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).
