The internal elements are isolated from the sample by a compressed silver iodide sensing membrane. This solid state sensor requires a separate reference electrode to complete the measurement system.\u003c\/p\u003e\n\u003cp\u003eHanna's solid state half-cell ISEs are designed for use with the HI5315 reference half-cell. The reference half-cell features a cone style junction. The skirted cone geometry of the reference forms the liquid junction with the test solution at the tip of the junction cone,  producing a highly stable reference potential and consistent flow rates of electrolyte into the solution. A simple press of the top portion of the ISE makes it easy to empty the electrolyte fill solution and replace when necessary.\u003c\/p\u003e\n\u003cp\u003eFor the HI4011 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. The HI4011 iodide solid state ISE can measure from 0.1µM (0.01 mg\/L) to1M (127, 000 mg\/L).\u003c\/p\u003e\n\u003cp\u003eConversion Table for I\u003csup\u003e-\u003c\/sup\u003e\u003c\/p\u003e\n\u003cdiv style=\"overflow-x: auto; margin: 0 0 32px;\"\u003e\u003ctable\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"200\"\u003e\n\u003ccol width=\"*\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eMultiply\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003emoles\/L (M) to ppm (mg\/L)\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003e1.269 x 10\u003csup\u003e5\u003c\/sup\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eppm (mg\/L) to M (moles\/L)\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003e7.88 x 10\u003csup\u003e-6\u003c\/sup\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003ch2\u003eFeatures at-a-glance\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFixed Sensing Modules\u003c\/strong\u003e - Solid state half-cell ISEs are electrodes that detect free ions in a solution.

An equilibrium occurs due to the highly limited solubility of the membrane material in the sample. When the ionic strength of the solution is fixed by the addition of ISA,  the voltage is proportional to the concentration of free ions in solution.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI4011\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Iodide Half-Cell Ion-Selective Electrode (ISE) - HI4011\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription\u003c\/td\u003e\n\u003ctd\u003e solid state; half-cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e Iodide (I\u003csup\u003e-\u003c\/sup\u003e) 1M to 1 10\u003csup\u003e-7\u003c\/sup\u003eM, 127,000 to 0.01 mg\/L (ppm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e 0 to 80 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003e epoxy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptimum pH Range\u003c\/td\u003e\n\u003ctd\u003e pH 2 to 13\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Length\/Overall Length\u003c\/td\u003e\n\u003ctd\u003e 120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Diameter\u003c\/td\u003e\n\u003ctd\u003e 12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable\u003c\/td\u003e\n\u003ctd\u003e coaxial; 1 m (3.3’)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003e BNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNotes\u003c\/td\u003e\n\u003ctd\u003e Approximate Slope -56 mV\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\/HI4011\"\u003eIodide Half-Cell Ion-Selective Electrode (ISE) - HI4011\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871287542129,"sku":"HI4011","price":73290.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi4011_2016.jpg?v=1792646068","url":"https:\/\/hannainst.in\/products\/iodide-half-cell-ion-selective-electrode-ise-hi4011","provider":"hanna","version":"1.0","type":"link"}
