Description
Lead electrode DX407 is an ion-selective electrode (ISE) with solid-state membrane for lead determination in laboratory ion analysis. This DX407-Pb half-cell uses a modular design: a common shaft paired with an ion-specific membrane module that defines selectivity for lead. Shaft material is POM / PVC. Operating temperature covers 0 … 50 °C, the optimal pH range is 2 … 8, and the measuring range extends from 1,0 to 1,0×10⁻⁵ mol/L. Every ion-selective electrode and membrane module is wet-chemically tested to meet strict protocols for multiple direct measurements and a typical titration application; each ISE receives a serial number and a quality certificate. The modular concept from manufacturer Mettler-Toledo OnLine keeps the shaft identical across half-cells while the screwed-on membrane module makes the sensor ion-specific—exchange the module to reconfigure the half-cell for another ion without replacing the entire electrode. Supplied as 1 pc with net weight 0,206 kg, the DX407 lead electrode supports flexible, quality-controlled ISE workflows in analytical laboratories requiring reliable lead ion measurement.

Questions about DX407-Pb ISE half-cell electrode
What is this article?
DX407-Pb 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.
