Introduction
XS Instruments, globally recognized as a leading brand in the field of electrochemical measurements, has
developed this new line of portable instruments completely produced in Italy, finding the perfect balance
between performance, attractive design and ease of use.
The robustness and integrity of the case, the integrated brightness sensor and the practical carrying case
make this instrument ideal for measurements directly in the field.
Thanks to the triple power supply and the ability to manually change the contrast and brightness of the
display, this instrument is also suitable for use in the laboratory.
The innovative high definition colour LCD display shows all the necessary information, such as the
measurement, the temperature, the buffers used for the last calibration (also custom), the condition of
stability.
Everyone can use these tools thanks to the instructions that appear directly on the display. The calibration
is guided step by step and the instrument configuration menu is easy to consult. In addition, a LED
indicates the status of the system to the user.
Up to 3 pH calibration points can be carried out between 10 automatically recognized values and 5 points
for Conductivity; in addition, buffers chosen by the operator can be used.
It is also possible to perform mV calibration for Redox sensors.
For an accurate measurement of the conductivity value, it is possible to work with 3 different cell
constants and to modify the compensation coefficient and the reference temperature.
It is possible to consult the calibration data anytime and the representation makes the calibration process
more efficient, through the icons of the buffers used.
Automatic or manual Data Logger function with values that can be stored in different GLP formats on the
internal memory (1000 data) or on the PC.
The ideal solution for an accurate and precise measurement is to use an XS Sensor electrochemical
electrode with an XS Instruments device and perform the calibrations with XS Solution certified
calibration solutions.

The housing is in ABS / PC (acrylonitrile butadiene styrene / polycarbonate). This material is sensitive to
some organic solvents, for example toluene, xylene and methyl ethyl ketone (MEK).
If liquids get into the housing, they could damage the instrument.
In case of prolonged non-use of the device, cover the BNC connectors with the special cap.
Do not open the instrument housing: it does not contain parts that can be maintained, repaired or replaced
by the user. In case of problems with the instrument, contact your local distributor.
It is recommended to use original spare parts only. Contact your local distributor for information. The use
of non-original spare parts can lead to malfunction or permanent damage to the instrument. Moreover, the
use of spare parts not guaranteed by the supplier can be dangerous for the user himself.
For the maintenance of the electrochemical sensors, refer to the documentation present in their packaging
or contact the supplier.
•Responsibility of the owner of the instrument
The person who owns and uses the tool or authorizes its use by other people is the owner of the tool and
is responsible for the safety of all users of the tool and third parties.
The owner of the instrument must inform users of the use of the same safely in their workplace and on the
management of potential risks, also providing the required protective devices.
When using chemicals or solvents, follow the manufacturer's safety data sheets.

Temperature measurement ATC – MTC
•ATC: The direct measurement of the sample temperature for all parameters is carried out through the
NTC 30KΩprobe, which can be either integrated into the sensor (electrode and / or cell) or external.
•MTC: If no temperature probe is connected, the value must be changed manually: keep pressed
or until the value starts to flash; then adjust it by continuing to use the directional keys; press
to confirm.
pH Parameter
pH 70 Vio; PC 70 Vio
On this series of devices, it is possible to use pH sensors with integrated temperature probe or to connect
two different sensors. Connect the pH electrode to the BNC type connector marked in green. Connect the
temperature probe to the RCA / CINCH Temp connector always marked with a green background.
The instrument is also able to recognize the DHS sensor, an innovative electrode that stores calibration data
and that can be used immediately after on any enabled instrument.

During calibration, press to exit and save the points calibrated up to that moment
(see calibration paragraph).
The instrument automatically recognizes 2 families of buffers (USA and NIST); in addition, the user has
the option of performing a manual calibration of up to 2 points with customizable values:
USA Buffers: 1,68 - 4,01 - 7,00** - 10,01 - 12,45 (Factory setting)
NIST Buffers: 1,68 - 4,00 - 6,86** - 9,18 - 12,46
**Neutral point always requested as first
In measure mode at the bottom left of the display, a series of
beakers indicates the buffers with which the last automatic and
manual calibration was carried out.

P1.3 Stability criterion in pH measurement
To consider the reading of a value truthful, we recommend waiting for the measurement stability, indicated
by the icon . When the measurement is not stable, four red flashing bands appear on the display.
Access this menu to change the measurement stability criterion:
“LOW”: choose this option to bring up the stability icon even in conditions of poor stability.
Readings included within 1.2 mV.
“MEDIUM” (default value): readings included within 0.6 mV.
“HIGH”: choose this option to display the stability icon only in conditions of high measurement stability,
readings included within 0.3 mV.
