INTENDED USE
Use of the pH/Redox probe type 8203 that does not
comply with the instructions could present risks to
people, nearby installations and the environment.
• The probe is used to measure:
- the pH in clean liquids or liquids containing solids,
sulphides or proteins.
- or the oxidation reduction potential in clean liquids
or liquids containing solids, sulphides or proteins
which may present low conductivity.
• This product must be used in compliance with the
characteristics and commissioning and use conditions
specified in the contractual documents and in the user
manual.
• Requirements for safe and proper operation are proper
transport, storage and installation as well as careful
operation and maintenance.
• Only use the product as intended.

Restraints
Observe any existing restraints when the product is exported.
Foreseeable misuse
• Do not use the pH / Redox probes in an explosive
atmosphere.
• Do not use fluid that is incompatible with the materials of
which the probe is made.
BASIC SAFETY INFORMATION
This safety information does not take into account:
• any contingencies or occurences that may arise during
assembly, use and maintenance of the devices.
• the local safety regulations that the operator must ensure
the staff in charge of assembly observe.
Danger due to high pressure in the installation.
Danger due to high temperatures of the fluid.
Danger due to the nature of the fluid.

Various dangerous situations
To avoid injury take care to:
• prevent any power supply switch on.
• carry out the installation and maintenance work by
qualified and skilled staff with the appropriate tools.
• use the device only if in perfect working order and in compliance with the instructions provided in the user manual.
• observe the general technical rules during the planning
and use of the device.
NOTE
Chemical compatibility of materials in contact with
the fluid.
• Systematically check the chemical compatibility of the
component materials of the probe and the fluids likely
to come into contact with it (for example: alcohols,
strong or concentrated acids, aldehydes, alkaline
compounds, esters, aliphatic compounds, ketones,
halogenated aromatics or hydrocarbons, oxidants and
chlorinated agents).

DESCRIPTION
Sphere of application
The pH/Redox probe is used to measure:
• the pH in clean liquids or liquids containing solids, sulphides or proteins.
• or the oxidation reduction potential in clean liquids or
liquids containing solids, sulphides or proteins which
may present low conductivity.
General description
• The pH probe is a glass membrane with variable
selectivity according to the pH. When the pH probe
is immersed in a solution, a difference in potential is
formed, due to the hydrogen ions (H+), between the
glass membrane and the solution. This difference in
potential, measured in relation to a reference electrode,
is directly proportional to the pH value (59.16 mV per pH
unit at 25°C).
• When a Redox probe is immersed in a solution, an
exchange of electrons occurs between the oxidised form
and the reduced form of an electrolyte. The resulting
voltage is the oxidation reduction potential.
