A manual about water alkalinity measurement
The Hanna Instruments HI 38013 is a compact test kit designed for monitoring phenolphthalein and total alkalinity in water. It includes indicators (phenolphthalein and bromophenol blue), reagents, a calibrated plastic vessel, and a syringe to determine the quantitative capacity of a sample to neutralize acid.

Read the milliliters of titration solution from the syringe and multiply by 20.
Read the milliliters of titration solution from the syringe and multiply by 20.
Fill the vessel to the 10 mL mark instead of 5 mL and multiply the milliliters of titration solution by 10.
