Description
WinLab® pH combination electrode is a glass single-rod measuring chain for laboratory pH determination. The glass electrode uses an S7 plug head and therefore requires a suitable adapter cable for connection to the meter. It is refillable with 3 mol KCl solution, allowing electrolyte maintenance during extended laboratory service. This configuration suits routine pH measurement in aqueous samples across analytical, quality-control and teaching environments where a classic refillable glass combination electrode is preferred. The unspecified glass shaft supports standard immersion practice in beakers, flasks and sample vessels. Supplied as a single piece from manufacturer Windaus under the WinLab® brand, the electrode integrates into existing electrode systems that already use S7-style plug-head cabling. Laboratories that standardise on modular plug-head connections can select the matching adapter cable for their instrument input. The refillable design supports consistent reference performance when electrolyte levels are checked and topped up according to normal laboratory practice for glass pH combination electrodes.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about WinLab® pH combination electrode
What is this article?
WinLab® pH combination electrode is the article on this page. Luminix Health distributes Windaus 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.
