How it works
The figure to the side shows a schematic representation of the operating principle.
The 3 tube inlets on the front of the
ION Director®
are connected to 3 dosing pumps of a
GHL Doser 2
(
2.1
). The precise dosing pumps handle the conveying of the liquids.
After starting the measuring process, first the sample tube is completely refilled, the water
previously present in the sample tube is returned to the aquarium (or the sump) through the
connection on the back (
Vent
). This ensures that a fresh sample is always used for the
measurement - and not older water that has been in the sample hose for a longer period of
time - and that the measurement result actually reflects the current situation in the tank; in
addition, no water is wasted during this flushing.
Afterwards, the sensor is calibrated and the measurement is carried out by slowly adding
reference liquids and the sample water.
