Reaction time:
5 minutes
Add 1 level blue micro-
spoon of K-2K, close the
cell with the screw cap.
Shake the cell vigorous-
ly to dissolve the solid
substance.
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.
Add 6 drops of K-1K,
close the cell with the
screw cap, and mix.
Check the pH of the
sample, specified range
:
pH 3 – 12.
If required, add dilute
sodium hydroxide
solution or sulfuric acid
drop by drop to adjust
