To maintain the high precision of the titrator,  a simple pump calibration procedure is performed with HI84500-55 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 sulfur dioxide levels in wine.\u003c\/p\u003e\n\u003cp\u003eThe HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method.
