Description
Sodium electrode DX223 ISE is an ion-selective half-cell electrode for determining sodium concentration in samples such as foodstuffs, biological fluids and cooling water. Construction follows the general layout of a conventional pH electrode, yet the membrane glass is formulated for higher sodium sensitivity. The DX223-Na sodium half-cell uses a glass shaft, operates over a temperature range of 0 … 80 °C and covers a measuring range from 1,0 to 1,0·10⁻⁷ mol/L, with an optimal pH window of 8 … 11. Response is fast and the electrode is maintenance-free, reducing day-to-day service effort. Net and gross weight are each 0,103 kg. Supplied as a single piece from manufacturer Mettler-Toledo OnLine, the sensor suits laboratories that quantify sodium alongside other electrochemical parameters. Country of origin is Switzerland. Typical deployments include food analysis, biological fluid testing and industrial cooling-water monitoring where selective sodium readout is required. The glass-shaft ISE format integrates readily into standard electrode holders and meters configured for ion-selective measurements.

Questions about DX223-Na ISE half-cell electrode
What is this article?
DX223-Na ISE half-cell electrode is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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.
