Features
The JUMO digiLine O-DO S10 is an intelligent sensor for measuring dissolved oxygen. The oxygen mea-
surement takes place in accordance with the optical measuring principle of luminescence quenching ac-
cording to ASTM D888-05. This results in the following benefits for the user:
•
No replacement of electrolytes
•
No polarization voltage required
•
No minimum inflow
•
Greater calibration intervals due to low drift behavior
•
Reliable measurement with long-term stability
The measured value for dissolved oxygen is automatically compensated to account for the temperature
influence. In addition, the measured value can be compensated by the oxygen sensor with regard to the
determining factors air pressure and salinity (if necessary using external sensors).
The JUMO digiLine O-DO S10 has 2 interfaces that can be used to transfer the measured value from
the sensor to the measuring device/automation device. Communication takes place using a digital inter-
face via RS485 Modbus RTU protocol or as an analog signal via the 4 to 20 mA two-wire current inter-
face.
Configuration, parametrization, and calibration data is stored in the electronic components in the sensor
of the JUMO digiLine O-DO S10. Sensor-specific specifications and measuring point information can
also be stored and called up. In addition, a log book with the last 10 successful calibrations is available;
this provides the user with an overview of the previous calibration history.
Furthermore, the sensor is equipped with the capability for self-diagnostics, in order to determine possi-
ble malfunctions. The information is output as a warning or error message.
The sensor is streamlined and has a robust construction. The sensor cap is easy to replace if it becomes
worn. The sensor body of the JUMO digiLine O-DO S10 consists of PVC material, which allows it to be
used in fresh water and salt water. A fixed cable with a 5-pole M12 connector is mounted on the sensor.
The electrical connection to a measuring or automation device is quick and easy to establish.
2 connection options are available for mounting in a fitting – the Rp1 thread on the sensor shaft or a
mounting set G1 available as accessories.
All wetted materials are suitable for fresh and salt water.
