The HI84533-55 is a 120 mL bottle of pump calibration standard solution that is used for both low and high range determination of formol number.
Formol number of wine and fruit juice, as performed on the HI84533 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. To achieve precise results, the instrument occasionally requires 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 HI84533-55 pump calibration solution to accurately determine the formol number of wines and fruit juices.
Replacement reagents required to operate the HI84533 include:
Low Range - 30.0 to 400.0 mg/L as N
High Range - 300 to 1000 mg/L as N
Pump calibration standard
pH adjustment reagent
Formol base reagent
