Description
SenTix® 20 plastic pH electrode with gel electrolyte and S7 plug head is a robust combination electrode for routine pH measurement in laboratory samples. The plastic shaft houses a maintenance-friendly gel electrolyte system that reduces refilling effort and supports stable readings across typical aqueous matrices. An S7 plug head allows flexible cable selection so the electrode can be matched to existing meters and connectors without a fixed lead. Supplied without a connection cable, the sensor is ready for laboratories that already stock compatible S7 leads or prefer modular cabling. From manufacturer WTW - a Xylem brand, the SenTix® 20 is intended for general laboratory pH work, quality control and teaching environments where a durable plastic body is preferred over glass shafts. Net weight is approximately 0,099 kg, making the electrode easy to handle at the bench. Use it for aqueous samples within the electrode’s specified operating range and pair it with a suitable pH meter and calibration buffers for reliable day-to-day measurements.

Questions about SenTix® 20, Epoxy pH combination electrode with gel electrolyte, S7 plug head, w
What is this article?
SenTix® 20, Epoxy pH combination electrode with gel electrolyte, S7 plug head, w is the article on this page. Luminix Health distributes WTW - 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.
