The HI84442-55 is a 100 mL bottle of pump calibration standard solution that is used for both low and high range determination of alkalinity in water.
Water alkalinity is an expression of a water’s acid-neutralizing capacity and it is determined by titration with standard acidic solutions. Alkalinity is an important parameter for control and treatment of potable water and wastewater because it indicates the buffering capacity of water, or the ability to resist a pH change. The ability to resist large swings in pH results primarily from the presence of bicarbonates and carbonates. A low water alkalinity signifies that the water is susceptible to pH change, while a high alkalinity indicates that water is able to resist a major change of pH.
Titratable alkalinity in waters, as performed on the HI84442 mini titrator, utilizes a simple sample preparation, a high quality titrant dosing pump, potentiometric endpoint detection, and automatic computations. To maintain the high precision of the titrator, a simple pump calibration procedure is required. The pump calibration involves the analysis of a known volume of a known solution and compensates for changes in pump dosing that may occur due to many factors including tube stretching or aging. This procedure should be performed regularly with the HI84442-55 pump calibration solution to accurately determine alkalinity levels in water.
