1.6 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.

1 Introduction
1.7 Design
The basic design of the sensor is as shown below:
1.8 Function principle
A coloring agent (luminophore) is applied to the oxygen-permeable sensor cap. A blue LED located in
the sensor body irradiates the luminophore. By absorbing energy, it changes from its basic state to an
excited state. Following a time delay, it returns to its basic state as it loses heat and emits the remaining
energy as red light (referred to as florescent radiation), which is detected by a photo diode in the sensor
body.
If the luminophore comes into contact with an oxygen module in the excited state, the energy transmis-
sion occurs directly onto the oxygen module without emission of the red light. The intensity of the flores-
cent radiation reduces as the oxygen concentration increases. The operating life of the florescent
radiation also reduces as the oxygen concentration increases. The measuring electronics modulate the
exciter radiation. The oxygen concentration can be calculated precisely from the phase difference be-
tween the exciter and florescence radiation.
The measurement electronics of the sensor supply both the compensated oxygen concentration as well
as the temperature value for the measurement medium, measured inside the sensor, to the connected
measuring or automation device via the digital interface.

1.9 Factors influencing oxygen measurement
The measurement of oxygen is influenced by the following factors:
• The temperature of the measurement medium.
• The salinity of the measurement medium.
• The air pressure.
For the measurement of the oxygen concentration (mg/l) in water, knowledge of the medium temperature
is required. If the result in % saturation is desired, the current air pressure is also required.
1.9.1 Temperature
The dissolved oxygen content in water is heavily dependent on temperature. The higher the temperature
of the measurement medium, the lower the solubility of oxygen and vice versa.
The JUMO digiLine O-DO S10 takes this physical dependence of oxygen measurement on temperature
into account and outputs a measurement signal that is already temperature-compensated.
The temperature required for compensation can be provided by the temperature probe integrated in the
sensor, or it can also be transferred externally from the JUMO digiLine or Modbus master device. Anoth-
er option is to enter a fixed temperature value while configuring the JUMO digiLine sensor.
1.9.2 Air pressure
Dissolved oxygen in water is determined by partial pressure measurement. The amount of oxygen dis-
solved in the water also depends on the pressure of the atmosphere above the water surface. At high
air pressure, more oxygen is dissolved in the water than at low air pressure.
The air pressure (hPa) is included in the calculation of the oxygen saturation (% sat.) and must therefore
also be taken into account when calibrating the sensor (Chapter Calibration).
To measure oxygen saturation in water, the air pressure (hPa) must be entered manually as a fixed pres-
sure value while configuring the JUMO digiLine sensor. Alternatively, the air pressure can also be trans-
ferred externally from the JUMO digiLine or Modbus master device.
1.9.3 Salinity
Salinity, in simple terms, is the salt content of the water. Salts dissolved in water generally lead to a re-
duction in the solubility of oxygen. Therefore, to determine the oxygen concentration (mg/l) in the saline
measurement medium, the salinity needs to be compensated. The calculation is based on the tempera-
ture-compensated electrolytic conductivity (unit mS/cm).
Salt compensation can be carried out either by entering a fixed temperature-compensated conductivity
value while configuring the JUMO digiLine sensor, or it can be transferred externally from the JUMO dig-
iLine master device.

NOTE!
Installation of the sensor may only be carried out by qualified personnel!
3.1 Mounting site and environmental conditions
A suspended fitting or an immersion fitting (particularly suitable for aeration tanks) from JUMO should
preferably be used for mounting the sensor in a basin, a tank, or a container.
An insertion location representative for the typical oxygen concentration should be planned for the im-
mersion operation.
Our own flow fittings should preferably be used for mounting the sensor in the supply line for the medium
being measured or in the bypass.
A mounting site for the fitting should be selected that enables easy access for any subsequent calibra-
tion. It must be ensured that support pillars and fittings are mounted securely and in a way that subjects
them to no more than low levels of vibration.
Electromagnetic fields, caused by equipment such as motors and transformers, should be avoided. The
ambient temperature at the mounting site and the relative humidity must correspond to the information
in the "Technical data" chapter.
CAUTION!
Risk of damage to the sensor membrane due to chemicals.
A damaged membrane can lead to incorrect measurement results.
The sensor membrane should be prevented from coming into contact with chlorine gas, organic sol-
vents, strong acids, and peroxides.
CAUTION!
Risk of damage to the sensor membrane due to mechanical influences.
A damaged membrane can lead to incorrect measurement results.
The sensor membrane should be protected from mechanical loads, such as an abrasive particle
stream in the measurement medium.

3.2 Sensor fittings
3.2.1 Suspended fitting
The suspended fitting holds the JUMO digiLine O-DO S10 oxygen sensor and is primarily used to take
measurements from open basins or channels. It can be attached to a support pillar by means of a cross
clamp and positioned far from the basin edge with the retaining bracket hanging from a chain
chapter 3.4 "Setup of a measuring point with support pillar", Page 29. Different immersion depths are
possible through the use of different immersion pipe lengths.
Please note the following when planning your set-up:
• The fitting must be easily accessible to allow the sensor or the fitting itself to be maintained and
cleaned regularly.
• Do not allow the fitting (and thus also the sensor) to swing against and hit the basin edge.
• When working with systems involving temperature, ensure that the fitting and sensor meet the re-
quirements.
• The system designer must check that the materials in the fitting and sensor are suitable for the mea-
surement (chemical compatibility, for instance).

Suspended fitting with cleaning kit
The suspended fitting is optionally available in a
version with cleaning kit. The cleaning kit en-
ables water/air flushing of the built-in sensor with a
maximum cleaning pressure of 3 bar and a maxi-
mum cleaning temperature of 60°C.
Immersion length and materials are identical to
those of the suspended fitting.
In addition, the cleaning kit is also available as a
retrofit kit for installation on an existing sus-
pended fitting.
The cleaning kit consists of a sensor holder with
spray head, a PVC fabric hose and pipe clips for
attaching the hose to the fitting.
