Portable Disolved Oxygen Monitoring Station


Custom designed Dissolved Oxygen Measurement Radio and Satellite Telemetry Transmitters for use equally within a sewage works oxygenation ditch or suspended in a lake, lagoon, pond or a river.

Putting Oxygen in Space – Portable Dissolved Oxygen Unit – Operable Anywhere Without Power or Batteries

Dissolved Oxygen level is critical of the wellbeing of aquatic life and the operational efficiency of biological processes involved in sewage treatment. Hence the ability to monitor the dissolved oxygen levels in a body of water, lagoon or oxygenation ditches,  in real-time is critical as it permits real-time control of oxygen levels using technology such as the Oxfiniti portable oxygen injection boxes or the surface aerators.

Within a Sewage Works

Portable dissolved oxygen monitoring units such as the one featured on this page can be also used to calibrate and control the profile of oxygenation ditches within sewage works. Calibration of  the ditches permits transducers to be optimally sited in order to maximise the benefits of controlling equipment such as paddles, bubblers and enriched oxygen injection units such as the Oxfiniti Box.

Data Formats

Data from the telemetry units can be replicated at the receiving point as either a 4-20mA loop analogue signal, passed into a PC logging package such as our Sentinel FM or exported in CSV or JSON format to a remote web server.

Mains Power Not Necessary

Our Dissolved Oxygen Transmitters are designed to operate from mains or batteries. When battery operated power is conserved by automatically switching on and off the power to the DO transducer. For example by switching to a reading rate of 5-minutes it is possible to reduce the power consumed by typically 99% without compromising accuracy.

Rapid Deployment

Portable units are ideal for temporary deployment following for example a pollution incident and the relatively small form factor and the camouflage coloured carry case makes it relatively easy to hide the unit out of sight of vandals.

Communication Options

  • Satellite SBD via LEO Satellite Networks using the RDNET3000 protocol
  • Licenced Radio Telemetry
  • Point to Point Telemetry
  • Drive-By Wireless Links
  • Cabled Telemetry

Easy to Calibrate

The units like that featured above, feature a unique retraction arm that assist the retrieval and retraction of the sensor for cleaning without tools or the risk of dropping the sensor into the ditch.
