A OXYMETER PROBE
1 PRESENTATION
The Oxymeter is a luminescence technology-based tool
that measures oxygen and that can be operated with a
smartphone or a tablet.
The Oxymeter is used to measure dissolved Oxygen
in liquid.
The Oxymeter has a dipping probe and a
power and communication box (not submersible)
2 MEASUREMENT IN A TANK
The Oxymeter can be used for dissolved Oxygen
measurement in a tank by dipping the probe in the wine.
To reach the equilibrium more fastly, gentle
agitation of the probe in the liquid can be
performed.
3 IN LINE MEASUREMENT
Thanks to dedicated accessories, the Oxymeter can be
used to perform in line measurements directly on the
pipe during wine transfer. These accessories are available
in various diameters and types of connectors.
The nut must be tightened by hand only to avoid any
damage to the probe. The probe must be positioned so
that it protrudes inside the tube of 5 to 10 mm.

2 USE OF OXYMETER
a. Modify the calibration
This step, must be done only in the event of replacement
of the CAP.
From the PARAMETERS menu, select Manual Calibration,
entering the calibration’s parameters shown on the Final
Inspection Protocol which comes with the replacement
CAP. It is also possible to select Barcode Calibration to
read the barcode provided with the new CAP.

b. Settings
Measurement
- Parameters can be modified by pressing the value
(exple Humid)
- Only the parameter Unit and sometimes Temperature
measurement must be modified.
- The change must be validated “save” or canceled
“cancel”
c. Start a measurement
Change O2unit Androïd IOS

From Live View menu, there are two ways to launch a
measurement
- Press START : a continuous measurement is launched ,
the device will perform measurements with a predefined
interval of measurement. The measurement will continue
until PAUSE or STOP is pressed . The measurement
results will be displayed on a chart. WARNING :
the measurement will continue even if Bluetooth is
disconnected.
- Press SINGLE : a single measurement is performed.I
In this mode, the data cannot be recorded. STOP and
PAUSE buttons are disabled.
In case of measurement started by pressing START
WARNING : once the measurement is started
by pressing START you can disconnect your
smartphone or tablet, the measurement will
continue and the data will be saved. Only an
action on STOP or PAUSE can interrupt the measurement.
d. Export data
From MEASUREMENTS menu, you can access all the
data recorded by the Oxymeter. The data are sorted by
timestamp. By selecting a file name, you can download
the data on your smartphone or tablet in order to :
- Display data on a chart (SHOW DATA)
- Export (EXPORT) format CSV, XLSX, PDF
- Delete (DELETE)
3 BATTERY
a. Management
In order to avoid a rapid battery discharge, it is necessary
to stop the measurement by pressing STOP (in Live View
menu) and to disconnect the Bluetooth connection from
your smartphone or tablet when the measurements are
finished.
b. Battery replacement and reload

Two types of battery are recommended for your Oxymeter
• PANASONIC Ni-MH 2700 rechargeable
• Energizer Ultimate Lithium
DO NOT MIX THE BATTERIES, NEVER RECHARGE non
rechargeable battery.
If the batteries are replaced with the alternative
recommended type, it is suitable to modify
the battery type in the settings (parameters/
system/change battery type)
When the battery level indicator shows a low level,
it is necessary to change all the batteries.
In the case of batteries replacement, perform a single
measurement SINGLE to refresh the battery indicator level.
In case of deep discharge of the batteries: the charger
may display NULL. You have to wait a few hours and
leave the batteries on the charger.
4 CALIBRATION CHECK
a- Quick check
You can check the calibration by performing an AIR
measurement, you need to set the temperature in manual
mode first and enter the current temperature value.
Choose the %O2oxygen unit, the value displayed should
be 20.7% O2more or less 0,5%.
b- Deep check
Add 100 mL water to a suitable vessel . To obtain air-
saturated water, blow air into the water using an air-pump
with a glass-frit (air stone), creating a multitude of small
air bubbles, while stirring the solution. After 20 minutes,
switch of the air-pump and stir the solution for another
10 minutes to ensure that the water is not supersaturated.
Choose the oxygen unit %EAS and perform measurements
after temperature stabilization the value should be
around 100% (+-4%).
