Basic safety instructions pH/ORP sensors and reference half cells
2 Basic safety instructions
2.1 Requirements for personnel
• Installation, commissioning, operation and maintenance of the measuring system may be
carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the specified

2.2 Designated use
The CPSx1D, CPSx1, CPS1x1D, CPFx1D and CPFx1 sensors are designed for the continuous
measurement of the pH value in liquids.
The CPSx2D, CPSx2, CPFx2D and CPFx2 sensors are designed for the measurement of the
oxidation-reduction potential (ORP) in liquids.
Together with the CPSx3 reference half cells, the CPSx4 and CPSx5 half cells are designed for
the measurement of the pH value (CPSx4) or the ORP (CPSx5) in liquids.
A list of recommended applications is provided in the Technical Information for the
relevant sensor.
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
