The liquid membrane sensor contains an organic polymer within the inert PVC matrix that is responsible for exchange of calcium ions across the membrane. A charge imbalance develops between the sample and the internal cell in response to the calcium ion activity. The potential change is proportional to the concentration of ions in solution.\u003c\/p\u003e\n\u003cp\u003eThe HI4004-51 calcium half-cell module easily screws onto the HI4004 probe body,  allowing for quick assemblage or replacement. Presoaking the calcium sensor in HI4004-45 conditioning solution or a calcium standard (0.01M) without ionic strength adjuster (ISA) for at least one half hour before calibration will help to optimize the sensor response. Refrigeration of the HI4004-51 calcium module will help extend its life.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI4004-51\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Calcium Module for Half-Cell ISE - HI4004-51\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\/HI4004-51\"\u003eCalcium Module for Half-Cell ISE - HI4004-51\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871281316209,"sku":"HI4004-51","price":28747.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi4004-51_1.jpg?v=1792646048","url":"https:\/\/hannainst.in\/products\/calcium-module-for-half-cell-ise-hi4004-51","provider":"hanna","version":"1.0","type":"link"}
