ALKALINITY TEST KIT (75 TEST)
✔ For fresh and sea water
✔ Suitable for alkalinity values from 50 ppm. to 25n ppm.
✔ If the water has the alkalinty highter than 300 ppm., dilution of 2-5 folds is required.
✔ Evaluate the value by titration. The number of drop multiply by 10 to obtain the total alkalinity in ppm. of CaCo3
