The special pH 4 and pH 7 buffers have a chloride background to verify the inner pH glass assembly housed within the ammonia and carbon dioxide gas sensing ISEs.\u003c\/p\u003e\n\u003cp\u003eBefore assembling an ammonia or carbon dioxide ISE for the first time,  or if reactivating after storage,  the inner glass assembly should be conditioned and tested as a pH electrode. The pH buffer packets can be added to 50 mL of deionized or distilled water and the sensor assembly carefully immersed in solution. When the mV measurement in each buffer solution is stable and recorded,  the mV difference can be calculated. A calculated mV difference equal or greater than 160 mV is acceptable for temperatures between 20 and 25℃.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI4000-47\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e ISE Slope Check Buffers with Chloride Background - HI4000-47\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertificate of Analysis\u003c\/td\u003e\n\u003ctd\u003e No\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e packets and beakers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 10 packets each buffer; 2 beakers\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\/HI4000-47\"\u003eISE Slope Check Buffers with Chloride Background - HI4000-47\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871276499313,"sku":"HI4000-47","price":8688.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi4000-47.jpg?v=1792646027","url":"https:\/\/hannainst.in\/products\/ise-slope-check-buffers-with-chloride-background-hi4000-47","provider":"hanna","version":"1.0","type":"link"}
