Sensor connection and measuring cable

4.2.1 Cable types
You require a screened special cable to connect pH and redox electrodes. You can use
the following multicore and preterminated cable types:
• CPK 1 for electrodes without Pt 100
• CPK 6 for:
– Sensopac with double reference electrode
– 1 pH individual electrode, 1 reference electrode, 1 Pt 100
– 2 pH combination electrodes with 1 Pt 100 or
2 pH combination electrodes with 1 shared reference electrode
• CPK 9 for electrodes with TOP 68 plug-in heads (ESA / ESS) and Pt 100
• CPK 12 for IsFET pH sensors and pH/redox glass electrodes with TOP 68 plug-in
heads (ESB) and Pt 100 / Pt 1000
