How it works
The 2 inlets and 1 outlet of the KH Director connect to 3 dosing pumps on the Doser 2 (2.1).
These 3 pumps are then responsible for accurately transferring fluid to and from the KH
Director.
The KH Director is first supplied with a sample of the aquarium water, the sample tube is
automatically deaerated.
Subsequently, with the slow addition of a reagent liquid and measurement of the pH value,
the KH value is precisely determined.
After the KHD has calculated the KH value, the sample water is pumped out once again and
then dispensed into a separate container for later disposal.
Finally, the content of the sample tube is pumped back into the aquarium, thus ensuring that
always "fresh" aquarium water is measured and the reading is up to date.
