The silver iodide sensing pellet produces a potential change due to the iodide ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable epoxy body.\u003c\/p\u003e \u003ch3\u003eThe HI-4011 is an iodide half-cell ISE.\u003c\/h3\u003e \u003cp\u003eThis electrode has a 1m cable and BNC connector.\u003c\/p\u003e \u003cp\u003eThe solid state sensor requires a separate reference electrode to complete the measurement system. Hanna’s solid state half-cell ISEs are designed for use with the HI-5315 reference half-cell.\u003c\/p\u003e \u003cp\u003eFor the HI-4011 to measure iodide accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the halide ionic strength adjuster (ISA) solution. The halide ISA ensures that the activity coefficient is constant so the concentration of free iodide ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements.\u003c\/p\u003e \u003cp\u003eThe HI-4011 iodide solid state ISE can measure from 0.1µM (0.01 mg\/L) to1M (127,000 mg\/L).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eParameter\u003c\/td\u003e\n\u003ctd\u003eIodide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSolid-state; Half-cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e1M to 1X 10-7M 127000 to 0.01 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptimum pH Range\u003c\/td\u003e\n\u003ctd\u003e2 to 13\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e0 to 80°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate Slope\u003c\/td\u003e\n\u003ctd\u003e-56\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody O.D.\u003c\/td\u003e\n\u003ctd\u003e12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInsertion Length\u003c\/td\u003e\n\u003ctd\u003e120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eEpoxy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable\u003c\/td\u003e\n\u003ctd\u003e1m coaxial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003eBNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePossible Applications\u003c\/td\u003e\n\u003ctd\u003eDetermination of free iodide ions in emulsified food samples (iodized table salt), plants and for titration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640062910837,"sku":"HI-4011","price":766.27,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/iodide-ise-half-cell.jpg?v=1791580164","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-4011-iodide-half-cell-ise","provider":"Test All Water","version":"1.0","type":"link"}
