To maintain the high precision of the titrator,  a simple pump calibration procedure is performed with HI84100-55 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,  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 HI84100 determines the free and total sulfur dioxide concentration in wine using the Ripper method. The HI84100 can be used in all wines,  including red,  which are difficult to test using traditional methods associated with a distinctive color change to determine the endpoint. Excess iodide added to the wine sample reacts with iodate introduced by the titrant to produce iodine:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e-\u003c\/sup\u003e + 5I\u003csup\u003e-\u003c\/sup\u003e + 6H\u003csup\u003e+\u003c\/sup\u003e → 3I\u003csub\u003e2\u003c\/sub\u003e + 3H\u003csub\u003e2\u003c\/sub\u003eO\u003c\/strong\u003e \u003cbr\u003e\u003cbr\u003e The iodine produced in the sample then reacts with sulfur dioxide in the wine according to the redox reaction below: \u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eH\u003csub\u003e2\u003c\/sub\u003eSO\u003csub\u003e3\u003c\/sub\u003e + I\u003csub\u003e2\u003c\/sub\u003e → H\u003csub\u003e2\u003c\/sub\u003eSO\u003csub\u003e4\u003c\/sub\u003e + 2HI\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eReplacement reagents required to operate the HI84100 include:\u003c\/p\u003e\n\u003cdiv style=\"overflow-x: auto; margin: 0 0 32px;\"\u003e\u003ctable\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"250\"\u003e\n\u003ccol width=\"185\"\u003e\n\u003c\/colgroup\u003e\n\t\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eTitrant solution\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84100-50\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eAlkaline reagent for total SO\u003csub\u003e2\u003c\/sub\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84100-51\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eAcid reagent for total SO\u003csub\u003e2\u003c\/sub\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84100-52\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eAcid reagent for free SO\u003csub\u003e2\u003c\/sub\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84100-53\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eStabilizer powder packets\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84100-54\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003ePump calibration standard\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84100-55\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI84100-55\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Pump Calibration Standard for Sulfur Dioxide Mini Titrator - HI84100-55\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription\u003c\/td\u003e\n\u003ctd\u003e Pump Calibration Standard for Sulfur Dioxide Mini Titrator \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e 500 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/manuals.hannainst.com\/HI84100-55\"\u003ePump Calibration Standard for Sulfur Dioxide Mini Titrator - HI84100-55\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871416844657,"sku":"HI84100-55","price":4676.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/dark_500ml_4.png?v=1792646570","url":"https:\/\/hannainst.in\/products\/pump-calibration-standard-for-sulfur-dioxide-mini-titrator-hi84100-55","provider":"hanna","version":"1.0","type":"link"}
