Dissolved Oxygen (DO) refers to the amount of molecular oxygen dissolved in water that is available for biological and chemical processes. It is a key indicator of water quality and plays a vital role in the survival of fish, microorganisms, and other aquatic life.
The concentration of dissolved oxygen is influenced by temperature, pressure, salinity, and biological activity. Low DO levels can indicate contamination, high organic load, or poor water circulation—leading to negative effects on ecosystems and industrial processes.
JUMO dissolved oxygen sensors are used in a wide range of applications, including:
• Wastewater treatment: Monitoring aeration in activated sludge tanks to optimize biological cleaning processes.
• Drinking water treatment: Controlling oxygen levels to prevent corrosion and ensure water quality.
• Aquaculture: Ensuring ideal living conditions for fish and aquatic organisms.
• Environmental monitoring: Assessing the ecological health of lakes, rivers, and coastal waters.
• Food and beverage industry: Monitoring process water to maintain product quality and hygiene.
Other fields of application include:
• Power plants and boiler feed water
• Biotechnology and fermentation processes
• Research and laboratory analysis
• Cooling water circuits
• Hydroponics and greenhouse systems
JUMO digiLine O-DO S10 – Intelligent oxygen sensor for dissolved oxygen (DO)
Product number:
802144
Cable length:
10 meters
The JUMO digiLine O-DO S10 is a modern, intelligent sensor for measuring dissolved oxygen. The measurement is based on the optical principle of luminescence quenching according to ASTM D888-05. This offers users numerous advantages:
No electrolyte replacement required
No polarization voltage necessary
No minimum flow required
Longer calibration intervals thanks to low drift behavior
Long-term stable and reliable measurement results
Temperature compensation is performed automatically, so that the measured value is always output temperature-compensated. In addition, the sensor can also correct the measured value with regard to air pressure and salinity (using external sensors).
The JUMO digiLine O-DO S10 has two interfaces for transferring the measured values to higher-level systems or automation solutions: digitally via an RS485 interface with Modbus RTU protocol or analogically via a 4...20 mA two-wire signal.
Configuration, parameterization, and calibration data are stored in the sensor's electronics. Sensor-specific information and measuring point identifiers can also be stored there and read out as needed. In addition, the sensor offers a logbook that documents the last ten successful calibrations, providing an overview of the calibration history.
To support operational safety, the sensor is equipped with a self-diagnostic function that issues warnings or error messages in the event of malfunctions.
The sensor features a slim, robust design. The sensor cap can be easily replaced when worn. The sensor body is made of durable PVC and is therefore suitable for applications in fresh and salt water. A permanently attached cable with a 5-pin M12 connector ensures quick and easy connection to measuring or automation devices.
The sensor offers two connection options for installation: an Rp 1 thread directly on the sensor shaft or, alternatively, an optionally available mounting kit with a G 1 thread.
