Description
ISE electrode for calcium, half-cell is a polymer-membrane ion-selective half-cell designed for the determination of free calcium in beverages, freshwater and seawater. The epoxy-resin/PVC body supports a measuring range from 1 M to 3 × 10⁻⁶ M, equivalent to 40080 to 0,12 mg/l. Best results are achieved in the pH window 4–10, with an operating temperature range of 0–40 °C. Approximate slope is +28. Connection is made via a 1 m coaxial cable fitted with a BNC plug; the immersion section measures Ø 12 mm × 120 mm. Supplied as one piece from manufacturer Hanna Instruments, this half-cell electrode provides a practical solution for food, beverage and environmental laboratories that require selective free-calcium readings. Net weight is 0,25 kg (gross 1,25 kg), making the sensor easy to integrate into existing electrode sets and storage systems without unnecessary bulk.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Calcium Half-Cell Ion Selective Electrode, Polymer Membrane
What is this article?
Calcium Half-Cell Ion Selective Electrode, Polymer Membrane 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.
