  • Measuring principle

    Optical oxygen measurement

  • Application

    Aeration tank, river monitoring, water treatment, fish farming.

  • Characteristic

    Digital, optical (luminescence) dissolved oxygen measurement.
    No flow needed - measurement possible in still water.

  • Measuring range

    0mg/l ... 20mg/l
    0%SAT ... 200%SAT

  • Measuring principle

    Oxygen-sensitive molecules (marker) are integrated in an optical active layer (fluorescence layer). The fluorescence layer surface is in contact with the medium. The sensor optics are directed at the back of the fluorescence layer. The sensor optics transmit green light pulses to the fluorescence layer. The markers respond (fluoresce) with red light pulses. The duration and intensity of the response signals depend directly on the oxygen contents or partial pressure.

  • Design
