1 SAFETY PRECAUTIONS
Carefully read these operating instructions completely
before operating this instrument. This is necessary to
avoid damage to it, as well as for user-safety.
Only use the instrument for the purpose for which it was
designed.
Only use the instrument in dry rooms in which there is no
risk of explosion.
Protect the instrument from dust, moisture and vapours.
Use a slightly moist lint-free cloth to clean the instrument.
Do not use aggressive cleaning agents or solvents.
Take care that no liquid penetrates in through the hous-
ing openings, as such penetration would result in dam-
age to Sensor.
Do not open the unit.
2 PURPOSE AND CHARACTERISTICS
The sensor measures the redox potential (ORP) of a solution
and sends the measured values via Bluetooth to any terminal
device, such as Tablets, smartphones, etc.
With the help of the sensor chemical reactions can be ob-
served, the ion activity can be determined or the oxidizing or
reducing properties of a solution can be determined.
Caution!

supplied ORP electrode can be connected.
4 NOTES ON OPERATION
This device fulfils all of the technical requirements that are
compiled in current EC guidelines. The characteristics of this
product qualify it for the CE mark.
This instrument is only to be put into operation under special-
ist supervision in a controlled electromagnetic environment in
research, educational and training facilities (schools, universi-
ties, institutes and laboratories).
The individual connecting leads are each not to be longer
than 2 m.
The instrument can be so influenced by electrostatic charges
and other electromagnetic phenomena (HF, bursts, indirect
lightning discharges) that it no longer works within the given
specifications. Carry out the following measures to reduce or
eliminate the effect of such disturbance: Ensure potential
equalization at the PC (especially with Laptops). Use screen-
ing. When a total failure of the instrument occurs, unplug it
and plug it back in again for a reset.
5 HANDLING
This section describes the start-up of the sensor and the re-
cording of measurement data. Please read this section thor-
oughly in order to avoid failures or operating errors.
5.1 Start-up
Switch the sensor on by pressing the on-button for more than
3 seconds. The Bluetooth LED lights up red. Start the soft-
ware and select the sensor.
A 9-digit code is
printed on the back of
the sensor (Fig.2). The
last 4 digits of the code
are displayed as
sensor designation in
the software (Fig.3).
This enables an exact
assignment of the
sensors with the software.
Fig. 2
Fig. 3
After the sensor has been selected in the software, the LED
flashes green to indicate that the connection has been estab-
lished correctly.
If the sensor is switched on and not connected, it switches off
automatically after 5 minutes.
5.2 Recording measurement data
Connect the supplied ORP electrode to the BNC socket of
the sensor and immerse the electrode completely in the liquid
to be measured.
5.3 Replacing the battery
Remove the battery
Open the sensor by turning the screw
cap on the back of the sensor
counterclockwise e.g. with a coin.
Fig. 4
Carefully lift the battery out of
the socket, e.g. with the aid of
a small screwdriver or small
scissors. Insert the screw-
driver as shown in Fig. 5.
Fig.
Insert new battery
Slide the battery under the golden
metal nose (Fig.6-1). Make sure
that the battery is completely under
the metal nose and is pushed
completely to the upper edge.
Fig. 6
Press the battery into the socket by applying light pressure
on the opposite side.
The battery slides under the two plastic lugs (Fig. 6-2), which
can also be noticed by a short "click”

Before closing the lid, make sure that
the seal in the lid is not bent and lies
cleanly on the edge of the lid. After
closing, turn the lid clockwise to
tighten it.

5.4 Care and storage of the electrode
The electrode can be stored in a dry place, but better in a 3
molar potassium chloride solution (3 molar KCl solution). Use
the protective cap provided for this purpose. In case of slight
soiling, clean carefully with a soft cloth with vinegar. In case
of more severe contamination, place the electrode in vinegar
presence for max. 20 min.
