Directions of use:
1. Rinse the measuring vessel with the water to be tested and fill up the 5 ml mark.
2. Add 1-2 drops of indicator and swirl. In presence of hardness higher than 3 ppm CaCO3 a wine red colour will appear (A blue colour indicates absence of hardness. With hardness lower than 3 ppm the colour of the sample shifts from violet, to grey to pink).
3. Add titrant drop by drop, mixing after each addition. Count the drops until the colour changes from red to blue. Each drop corresponds to 10 ppm.
4. For softened water, fill the vessel to the 10 ml mark and add 2-4 drops of indicator. Each drop of titrant corresponds to 5 ppm.
