Check the pH of the
sample, specified range
:
pH 3 – 9.
If required, add dilute
sodium hydroxide
solution or hydrochloric
acid drop by drop to
adjust the pH.
Pipette 1.0 ml of the
sample into a reaction
cell, close with the screw
cap, and mix.
Reaction time:

Cell Test
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer.
Add 1.0 ml of H-1K with
pipette, close the cell
with the screw cap, and
mix.
