    Digital, optical, calibration free – dissolved oxygen senors for the IQ Sensor Net

    Calibration-free, reliable, DIN compliant – the optical FDO® oxygen sensors for the IQ Sensor Net to regulate biological cleaning steps:

    • Calibration and flow free
    • Insensitive to air bubbles
    • Low usage costs

    FDO® sensors are the perfect solution for measuring dissolved oxygen. In addition to being free of calibration and flow, with their 45° membrane, they are also insensitive to air bubbles. Therefore, you will not require any additional installation equipment. The robust design of this sensors allows the use with an overpressure of up to 10 bar. The special membrane has a unique stability and thus ensures stable measured values.

    Models:

    • FDO® 700 IQ optical oxygen sensor for the IQ Sensor Net to regulate biological cleaning steps.
    • FDO® 701 IQ optical oxygen sensor for the IQ Sensor Net with a faster response time.
    • FDO® 700 IQ SW and FDO® 701 IQ SW: The sea water models are optimized for use in special media such as desalination plants, seawater or brackish water, fish farming or high salt content. All wetted parts are made of titanium and plastic and are therefore extremely resistant to corrosion.

    Applications:

    • Wastewater, e.g. regulation of biological treatment
    • Drinking water
    • Aquaculture, e.g. monitoring of water quality
    • Surface water, e.g. river water monitoring
    • Industry
