Description
pH combination electrode GEL is a laboratory measuring electrode designed for routine pH determination in aqueous samples and process solutions. Supplied as a complete combination unit, it integrates the measuring and reference functions in one body, simplifying setup on standard laboratory pH meters. The electrode is fitted with a fixed cable terminated in a BNC connector, allowing direct connection to instruments that accept this common laboratory interface without additional adapters. Offered as a single piece and weighing 0,100 kg, the sensor is convenient for benchtop workstations, teaching laboratories, and quality-control environments where reliable pH readings are required. The GEL designation identifies the gel-filled reference system used in this model, supporting straightforward handling during everyday measurements. This electrode from manufacturer Dostmann belongs to the pH electrodes category within laboratory measuring instruments and sensors, making it a practical choice for general analytical workflows, sample screening, and educational demonstrations. Its compact form and fixed BNC cable support quick installation and tidy cable management around the meter. Use it wherever a durable combination pH electrode with a fixed BNC lead is specified for routine laboratory practice.
This article belongs on pH electrodes & sensors, in pH & electrochemistry.

Questions about pH combination electrode GEL, with fixed cable (BNC), 1 unit(s)
What is this article?
pH combination electrode GEL, with fixed cable (BNC), 1 unit(s) is the article on this page. Luminix Health distributes Dostmann 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.
