Total Titratable Very Low Alkalinity Titrator
The HI 84442 is a dedicated mini titrator and pH meter designed for very low levels of alkalinity displayed as 5.0 to 20.00 mg/L as CaCO3 or 0.1 to 0.4 meq/L as CaCO3. It utilizes an electrometric titration with a pH electrode to determine the total titratable alkalinity in water. As 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 of 4.5 pH. (known as bromcresol green alkalinity).
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 reagent HI 84442-50.
