| Application
|
1) Take the 20 ml measured transparent container from the set box.
2) Add the water sample to be analysed up to the 5 ml mark.
3) Total Hardness Test without Alkalinity; 1 drop is added and mixed by holding the dropper mouth of the titrimetry bottle at a right angle of 90 degrees. Care should be taken to ensure that the drops do not have air bubbles.
4) If a red-pink colour is formed, continue to add dropwise the Total Hardness Test Kit without Alkalinity; titrimetric.
5) Stir after each drop.
6) Continue dripping until the colour turns bluish green.
7) When a bluish green colour is formed, the titration is terminated. |
| Microbiological Properties
|
The number of drops spent gives the total hardness of the water sample.
1 Drop = 1 AS (GERMAN HARDNESS) = 10 mg/l CaO = 1,79 FS
Hardness Presence Pinkish red. End Point Bluish green
