Description
The Lithium electrode DX207 is an ion-selective electrode (ISE) with polymer membrane for lithium ion determination in laboratory applications. This modular half-cell comprises a shaft and a replaceable membrane module, so the sensor can be adapted to other ions by fitting the corresponding membrane kit. Every ion-selective electrode and membrane module is wet-chemically tested to meet strict working protocols covering several direct measurements and a typical titration application. Each unit is assigned a serial number and supplied with a quality certificate. Shaft material is POM/PVC; the electrode operates from 0 to 50 °C over a measuring range of 1,0 to 1,0E-05 mol/L and an optimal pH range of 2 to 12. Offered as a single piece with a net weight of 0,11 kg, the DX207 lithium half-cell from manufacturer Mettler-Toledo OnLine supports ion-specific analysis. The shaft remains identical across half-cells while the membrane module defines selectivity, enabling straightforward conversion to other ISE configurations when required.

Questions about DX207-Li ISE half-cell electrode
What is this article?
DX207-Li 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.
Which category should I open next?
