IQ SensorNet VARiON® Plus Sensors

Ammonium, Nitrate, Potassium, and Chloride probe for IQ SensorNet systems

• Overview

  The VARiON is a rugged ion selective electrode (ISE) probe for the IQ SensorNet process monitoring system. The VARiON provides continuous and reagentless monitoring of Ammonium, Nitrate, Potassium and Chloride simultaneously. The most precise and reliable electrodes on the market. The individually replaceable electrodes have a typical lifetime of 18 to 24 months and are warrantied for 1 year, minimizing maintenance efforts and ownership costs. The VARiON is a good choice for simultaneous nitrification/denitrification monitoring and process control of aeration, mixed liquor recirculation, and external carbon dosing.

  • Measurement and display of ammonium, nitrate and 1 compensation electrode (potassium or chloride); cross-compensation with compensation electrode on separate probe within the same IQ network
  • Individually, user-replaceable measurement and reference electrodes
  • VARiON reference system is very stable over long periods of time
  • Digital probe recognizes electrodes
  • Simple in-situ calibration
  • Integrated NTC temperature sensor for temperature compensation
  • 2-year warranty on the probe, 1-year on electrodes
