Use coaxial cable or triaxial cable to connect the electrode. Triaxial cable is recommended
in environment with problems caused by electromagnetic interferences. Refer to
Figure 11.
Note: For a correct pH measurement a ferrite clamp filter (included) must be added on cable on the
side of pH or redox sensor.
Note: For a correct temperature measurement a ferrite clamp (included) filter must be added con
cable on the instrument side at Pt1000 sensors.
