Description
ISE electrode for iodine, half-cell is a solid-state ion-selective half-cell electrode intended for determination of free iodine ions in emulsified foods such as iodised table salt, in plant material, and as an indicator during titrations. The epoxy resin body houses the sensing element and supports routine laboratory ion analysis across a broad concentration window from 1 M to 1 × 10⁻⁷ M, corresponding to 127000 to 0,01 mg/L. Optimal pH operation spans 2 to 13, while the temperature range covers 0 to 80 °C, with an approximate slope of −56. Immersion geometry is Ø 12 mm × 120 mm, and the electrode is fitted with a 1 m coaxial cable terminating in a BNC connector for direct meter connection. For complete potentiometric measurement this half-cell must be paired with reference electrode HI5315. Offered as a single piece from manufacturer Hanna Instruments, the sensor suits food quality control, agricultural testing and titration workflows that require selective free-iodine response without integrated reference elements.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Iodide Half-Cell Ion Selective Electrode, Solid State
What is this article?
Iodide Half-Cell Ion Selective Electrode, Solid State is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
