The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI-84500 in determining the exact concentration of sulphur dioxide. The pump calibration procedure should be performed anytime the titrant or ORP electrode is replaced.\u003c\/p\u003e \u003ch3\u003eCalibration Standard for HI-84500-02 mini titrator for wine analysis.\u003c\/h3\u003e \u003cp\u003eAnalysis of sulphur dioxide in wine, as performed on the HI-84500 mini titrator, utilises 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 performed with HI-84500-55 pump calibration solution. The pump calibration procedure involves the analysis of a known volume of a known solution. The pump calibration procedure should be performed anytime the titrant, syringe, tubing or ORP electrode is replaced. Periodic calibrations should be performed in order to accurately determine the free and total sulphur dioxide levels in wine.\u003c\/p\u003e \u003cp\u003eThe HI-84500 determines the free and total sulphur dioxide concentration in wine using the Ripper method.
