9.1.2 FLOW-THROUGH ADAPTER FOR CONDUCTIVITY AND TEMPERATURE MEASUREMENT
The adapter is suitable for measuring pressure, temperature and conductivity in flow-though mode.
With immersion usage of the probe it is suitable for measuring temperature and conductivity
concurrently. The preferred orientation of the adapter is vertical. The axial connector must point down
(see picture). In flow-through mode the axial connector is to be used as inlet meanwhile the side
connector is to be used as outlet. Before measurement it is necessary to shake the adapter slightly,
so that air bubbles trapped inside can pass off through the outlet.
For immersion usage the probe must be disconnected from the flow-through.
Never touch the carbon ring electrode surfaces with your fingers or other objects.
Do not buckle the probe cable.
