Description
L 6880 is a pH combination electrode equipped with a plug head, glass shaft and three ceramic diaphragms for accurate laboratory pH determination. The sensor uses liquid KCl 3 mol/l electrolyte and the Silamid® reference system, paired with a spear-shaped A-glass membrane that facilitates penetration into semi-solid or viscous samples. It covers the pH range 0 to 14 and operates from -5 to +80 °C. Overall length is 120 mm with a stepped diameter of 12/8 mm, allowing convenient immersion in standard vessels. This configuration from manufacturer SI Analytics - a Xylem brand delivers stable potentials and rapid response in aqueous and lightly viscous media. The ceramic diaphragms maintain low junction resistance while the glass body provides chemical resistance. Supplied as one piece, the electrode is intended for routine pH measurements, quality-control laboratories and applications where a plug-head connection to conventional meters is preferred. Its robust mechanical design supports repeated use under typical laboratory conditions without compromising measurement integrity.

Questions about L 6880, pH-combination electrode with plug head with glass shaft, 3 x ceramic
What is this article?
L 6880, pH-combination electrode with plug head with glass shaft, 3 x ceramic is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand 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.
