The HI84532-55U is a 230 mL bottle of pump calibration standard solution that is used for both low and high range determination of acidity in fruit juice.
Titratable acidity in fruit juice, as performed on the HI84532 mini titrator, utilizes a simple sample preparation, a high quality titrant dosing pump, potentiometric endpoint detector, and automatic computations. To maintain the high precision of the titrator, a simple pump calibration procedure is required. A change of measurement range requires a different titrant along with a pump recalibration. 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 HI84532-55U pump calibration solution to accurately determine acidity levels in fruit juice products.
