Description
Calcium electrode DX240 ISE is a polymer-matrix membrane half-cell for determining calcium concentration in samples such as milk, serum and soil. The DX240-Ca sensor features an ion-selective membrane reinforced with a fine fabric mesh to improve mechanical stability and service life, paired with a robust POM/PVC plastic shaft for laboratory and field use. Temperature range is 0 to 50 °C, measuring range extends from 1,0 to 1,0×10⁻⁶ mol/L, and the optimal pH interval is 2 to 12. These specifications support calcium ISE measurements in food, clinical-related and environmental matrices. Available as one piece from manufacturer Mettler-Toledo OnLine, the electrode combines reinforced membrane construction with a durable shaft for everyday ion-selective workflows. Net weight is 0,238 kg. The reinforced polymer matrix and sturdy housing help deliver consistent performance where reliable calcium quantification is required in quality control and analytical laboratories.

Questions about DX240-Ca ISE half-cell electrode
What is this article?
DX240-Ca 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.
