Description
pH single-rod measuring cell SenTix 20 is a laboratory pH electrode configured with an S7 plug head for connection to compatible meters via a separately ordered cable. The combination electrode design supports routine pH measurement in aqueous samples across research, quality control, and general laboratory environments. Supplied as one unit without connecting cable, it allows flexible pairing with the appropriate lead for the instrument in use. This SenTix 20 sensor from manufacturer WTW belongs to the established range of pH electrodes used with measuring instruments and sensor accessories. The S7 plug-head interface is a practical choice when laboratories standardise on modular electrode–cable setups. Typical applications include buffer checks, process samples, educational practicals, and day-to-day pH monitoring where a robust single-rod cell is required. Clear identification of the SenTix 20 model and S7 head helps ensure correct spare-part selection and integration into existing WTW or S7-compatible measurement chains without unnecessary adapters.
This article belongs on pH electrodes & sensors, in pH & electrochemistry.

Questions about pH single-rod measuring cell, SenTix 20, with S7 plug head, 1 unit(s)
What is this article?
pH single-rod measuring cell, SenTix 20, with S7 plug head, 1 unit(s) is the article on this page. Luminix Health distributes WTW 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.
