  • Description

    Replacement electrodesfor ion selective NH4/NO3 sensors of the IQ SENSOR NET

    The replacement electrodes for the digital ISE sensors convince with reliable measurements:

    • Long lifetime (18 months)
    • Fast exchange
    • No drift
    • Easy matrix adjustment

    These especially stable electrodes ensure long operation times and a simple cleaning method. To measure, simply install the respective electrode into the IQ SENSOR NET, everything else will take place automatically. In the measured value display, the values that have already been compensated, are displayed, you can select potassium or chloride output. These values also stand for the signal output per 0/4-20 mA output or digital output (Profibus, Modbus RTU, Ethernet/IP, Modbus TCP, PROFINET) is directly available.

    The electrodes are replacement electrodes for the ISE sensors VARiON®, AmmoLyt® and NitraLyt®. Thereby, all 5 electrodes (1 reference, 2 measuring, 2 compensation electrodes) are basically usable for the 2 parameter sensor VARiON®. The measuring electrode VARiON®Plus NH4 and the compensation electrode VARiON®Plus K can further be used for the ammonium sensor AmmoLyt®. The measuring electrode VARiON®Plus NO3 and the compensation elektrode VARiON®Plus Cl are also fitting into the nitrate sensor NitraLyt®. The reference electrode can be connected to all 3 sensors.

    Electrodes:

    Reference electrode VARiON® Ref for mounting into sensors VARiON®Plus 700 IQ, NitraLyt®Plus 700 IQ, AmmoLyt®Plus 700 IQ

    Ammonium electrode VARiON®Plus NH4 for mounting into sensors VARiON®Plus 700 IQ and AmmoLyt®Plus 700 IQ, measuring range: 0.1 - 2,000 mg/l NH4-N

    Potassium electrode VARiON®Plus K for mounting into sensors VARiON®Plus 700 IQ and AmmoLyt®Plus 700 IQ, measuring range: 1 - 1,000 mg/l K+

    Nitrate electrode VARiON®Plus NO3 for mounting into sensors VARiON®Plus 700 IQ and NitraLyt®Plus 700 IQ, measuring range: 0.1 - 1,000 mg/l NO3-N

    Chloride electrode VARiON®Plus Cl for mounting into sensors VARiON®Plus 700 IQ and NitraLyt®Plus 700 IQ, measuring range: 1 - 1,000 mg/l Cl-
