This internal glass pH assembly provides the sensing and reference components for the ammonia combination ISE.\u003c\/p\u003e\n\u003ch4\u003eTheory of Operation\u003c\/h4\u003e\n\u003cp\u003eA gas sensor works due to the partial pressure of the measured gas in solution. The dissolved gas in the sample diŽffuses into the membrane and changes the pH in a thin film of unbuffered electrolyte on the surface of the internal pH sensor. Diffusion continues until the partial pressure of the sample and the thin film of electrolyte are the same. The pH change is proportional to the concentration of dissolved gas in the sample solution.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eHI4000-51\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003eReplacement pH Assembly for Ammonia ISE - HI4000-51\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/manuals.hannainst.com\/HI4000-51\" target=\"_blank\" rel=\"noopener\"\u003eReplacement pH Assembly for Ammonia ISE - HI4000-51\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871276597617,"sku":"HI4000-51","price":49080.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi4000-51.jpg?v=1792646029","url":"https:\/\/hannainst.in\/products\/replacement-ph-assembly-for-ammonia-ise-hi4000-51","provider":"hanna","version":"1.0","type":"link"}
