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:
3 minutes

Cell Test
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer
= Result total hard-
ness
Add 1.0 ml of H-1K with
pipette, close the cell
with the screw cap, and
mix.
Measuring 0.12 – 5.36 mmol/l
range: 0.7 – 30.1 °d
0.9 – 37.6 °e
1.2 – 53.7 °f
Total Hardness
Differentiation between Ca- and Mg-hardness
Add 3 drops of H-2K to
the already measured
cell, close the cell with
the screw cap, and mix.
Place the cell into the
cell compartment. Align
the mark on the cell with
that on the photometer
= Result magnesium
= Result calcium
Differentiation possible only in mmol/l.
A differentiation between calcium- and magnesium-hardness can be performed on the photometer. Prior to meas-
uring, select the differentiation measurement and choose the corresponding citation form.
