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

  • Overview

    The VARiON is an 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.

    • Accurate and Reliable - Measure ammonium and nitrate plus 1 compensation electrode (potassium or chloride).
      The VARiON reference system is very stable over long periods
    • Cost Savings - Individually user-replaceable electrodes have a typical lifetime of 18 to 24 months and are
      warrantied for 1 year, minimizing maintenance efforts and ownership costs
    • Smart Technology - Digital probe automatically recognizes electrodes
    • Protected Investment - Backed by a 2-year probe warranty and a 1-year electrode warranty
    • Rated Class I, Division 2 (CID2) - Conforms with NFPA standard 820 for CID2, groups A, B, C, D, and T6 to
      reduce the potential effects of fire or explosion for hazardous locations in wastewater applications

    The sensor is part of our IQ SensorNet family of products and works directly with our advanced wastewater process monitoring and control platform the IQ SensorNet 2020 3G controller or our simplified IQ SensorNet 282/284 controller.

    Additional IQ SensorNet ISE sensors include the AmmoLyt and NitraLyt
