The Hanna Instruments HI 84431 is a dedicated Mini Titrator and pH meter designed for low to high levels of alkalinity. The Hanna Instruments HI84431 utilizes an electrometric titration with a pH electrode to determine the total titratable alkalinity in water. Titrant is slowly added to the sample solution the pH and temperature are carefully monitored. The software analyzes the resulting pH curve and determines the volume of titrant required to reach the endpoint. The user can choose either 8.3 pH (known as phenolphthalein alkalinity) or 4.5 pH (known as bromcresol green alkalinity as endpoints).

The dispensed titrant volume is used to automatically calculate the water alkalinity, which can be displayed in mg/L CaCO3 or meq/L. Titrations are conducted using the low range reagent Hanna Instruments HI 84431-50 (10 to 500 mg/L as CaCO3) or the high range reagent HI 84431-51 (400 to 4000 mg/L as CaCO3).
