The DO30G sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works, effluent activated sludge process, and potable water treatment. It is also effective in river monitoring, intake protection, fish farming and other fields where water quality is important. This galvanic cell has a fast response time and good long-term stability and features replaceable diaphragm and cable for easy maintenance. A temperature sensor is incorporated for compensation. The DO30G sensor can be used in either the floating ball fitting or in the immersion fitting.


  • Fast response time
  • Good long-term stability
  • Easy membrane change
    PB30/PB350G/PB360G Floating Ball

    The floating ball holder for the DO30 features a design which minimizes fouling by the process. A brass ring around the sensor facilitates a check for membrane integrity, and helps to eliminate any deposits of algae, making a cleaning system unnecessary for the model PB30. Maintenance is very simple, with only periodic inspection and calibration needed.


    • Easy to install
    • Easy calibration
    • Sensor diagnosis for membrane integrity
    FD30/PH8HG/DOX8HS Immersion Adapter

    The immersion fitting is designed for installing the DO30G sensor in tanks, open vessels and drains. It can be supplied in lengths between 0.5 and 2.0 meter. Flange mounting is also possible. In applications with a heavy load of solids the use of a cleaning system is recommended, so an option, a “jet cleaner” is available for the immersion fitting. The use of this device can extend the continuous measurement period and eases maintenance.


    • Various immersion depths
    • Flange mounting possible
    • Cleaner option
    • Sensor diagnosis for membrane integrity
