You require screened special measuring cables to connect pH and ORP electrodes to the
transmitter. The following multi-core and ready-to-use cable types can be used:
Sensor type
Electrode without temperature sensor
Electrode with temperature sensor Pt 100
and TOP 68 plug-in head
ISFET sensor with temperature sensor
Pt 100 / Pt 1000 and TOP 68 plug-in head
pH individual electrode with separate
reference electrode and separate
temperature sensor
