Test
Quality assurance:
To check the measurement system (test reagents, meas-
urement device, and handling) a freshly prepared standard
solution can be used (see section “Standard solutions”).
Fill approx. 10 ml of
distilled water into a
24-mm cell (do not add
any reagents!), close
with the screw cap.
(Blank cell)
Select method 3 5 0 .
Insert the cell containing
the sample into the cell
compartment. Align the
mark on the cell with
that on the photometer.
Press Test .
Add 1 level blue micro-
spoon of O
3
-2, close
with the screw cap.
Add 2 drops of O
3
-1,
close with the screw
cap, and mix.
Shake the cell vigor-
ously to dissolve the
solid substance.
Important:
Very high ozone concentrations in the sample produce
yellow-colored solutions (measurement solution should be
red) and false-low readings are yielded. In such cases the
sample must be diluted (plausibility check).
Insert the blank cell into
the cell compartment.
Align the mark on the
cell with that on the pho-
tometer. Press Zero .
Check the pH of the
sample, specified range:
pH 4 – 8.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
the pH.
