A calibrated dosing pump allows for the accurate determination of the amount of titrant used when performing a titration. The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI84500 in determining the exact concentration of sulfur dioxide. The pump calibration procedure should be performed anytime the titrant or ORP electrode is replaced.\u003c\/div\u003e\r\n\u003cul\u003e\r\n\t\u003cli\u003e\r\n\t\t\u003cdiv\u003e\r\n\t\t\tStandardized solution\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\t\u003cdiv\u003e\r\n\t\t\tClearly marked expiration date and lot number\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\t\u003cdiv\u003e\r\n\t\t\tAir tight bottle with tamper-proof seal to ensure quality\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cdiv\u003e\r\n\t\u003cdiv\u003e\r\n\t\tAnalysis of sulfur dioxide in wine, as performed on the HI84500 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 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.
