Fluidics
The sample flows through the sample inlet [F] into the constant head
[A]. Adjust the flow regulating valve [D] so that always a small part of
the sample flows through the overflow tube [B] into the drain [H]. A
part of the sample flows through the photometer inlet [C] into the mix
-
ing chamber [E], where reagent [K] is added and mixed with the
sample. The mixed sample then flows through the coiled tube to the
photometer [N]. Shortly before entering the photometer, reagent [J] is
added to the mixture through a T-piece.
In the photometer [N], the ozone concentration is measured. After
the measurement, the sample flows through the outlet of the pho
-
tometer where it is aerated through air inlet [P] to generate bubbles.
Then the sample flows through the bubble detector [M] into the pho
-
tometer drain [I].
