1 Overview
1.1 pH/Cond 3320 meter
The pH/Cond 3320 meter enables you to perform measurements (pH, U, ISE,
conductivity) quickly and reliably.
The pH/Cond 3320 provides the maximum degree of operating comfort, reli-
ability and measuring certainty for all applications.
1.2 Sensors
A measuring system ready to measure consists of the pH/Cond 3320 meter
and a suitable sensor.
Suitable sensors are pH electrodes, ion selective electrodes (ISE), ORP elec-
trodes and conductivity measuring cells.

2 Safety instructions
2.1 Safety information
2.1.1 Safety information in the operating manual
This operating manual provides important information on the safe operation of
the meter. Read this operating manual thoroughly and make yourself familiar
with the meter before putting it into operation or working with it. The operating
manual must be kept in the vicinity of the meter so you can always find the infor-
mation you need.
Important safety instructions are highlighted in this operating manual. They are
indicated by the warning symbol (triangle) in the left column. The signal word
(e.g. "CAUTION") indicates the level of danger:
NOTE
indicates a possibly dangerous situation where goods might be damaged
if the actions mentioned are not taken.
2.1.2 Safety signs on the meter
Note all labels, information signs and safety symbols on the meter and in the
battery compartment. A warning symbol (triangle) without text refers to safety
information in this operating manual.
2.1.3 Further documents providing safety information
The following documents provide additional information, which you should
observe for your safety when working with the measuring system:
• Operating manuals of sensors and other accessories
• Safety datasheets of calibration or maintenance accessories (such as buffer
solutions, electrolyte solutions, etc.)
WARNING
indicates a possibly dangerous situation that can lead to seri-
ous (irreversible) injury or death if the safety instruction is not
followed.
CAUTION
indicates a possibly dangerous situation that can lead to
slight (reversible) injury if the safety instruction is not fol-
lowed.

2.2 Safe operation
2.2.1 Authorized use
This meter is authorized exclusively for pH, ISE, ORP and conductivity
measurements in a laboratory environment.
Only the operation and running of the meter according to the instructions and
technical specifications given in this operating manual is authorized (see
section 13 TECHNICAL DATA, page 71).
Any other use is considered unauthorized.
2.2.2 Requirements for safe operation
