2. Let the water flow for at least 30 seconds.
3. Take a water sample with the test tube:
a Fill the test tube up to the °dH mark to determine the water hardness in °dH.
b Fill the test tube up to the marking °f (x 0.1 = mol/m³) in order to determine the
water hardness in °f, mol/m³ or mmol/l.
7.7.3 Determining the water hardness in °dH/°f
1. Add one drop of titration solution (1 drop = 1 °dH = 1 °f).
2. Shake the test tube the until titration solution is mixed with the water.
3. In case of red colouring, repeat steps 2 and 3 and count the drops until the colour
changes to green.
» If the colour changes to green, the water hardness has been determined.
The number of drops corresponds to the degree of hardness in °dH or °f.
Example:

Test tube filled up to the °dH mark: 6 drops = 6 °dH.

Test tube filled up to the °f mark: 6 drops= 6 °f.
7.7.4 Determining the water hardness in mol/m³ (mmol/l)
1. Determine the water hardness in °f as described.
2. Divide the °f measured by 10.
The water hardness in °f divided by 10 corresponds to the degree of
hardness in mol/m³ (=mmol/l). Example:

6 drops = 6 °f = 0.6 mol/m³ = 0.6 mmol/l.
7.7.5 Entering the water hardness

3. Confirm with ENTER.
4. Enter the index value of the soft water hardness with ▼ and ▲.
5. Confirm with ENTER.
