Description
SenTix® H is a precision pH electrode fitted with a ground-joint diaphragm, developed for measurements in the highly alkaline range and in samples with high salt concentrations. The ground-joint junction provides a defined electrolyte outflow and helps maintain stable contact even in demanding matrices where conventional ceramic diaphragms may clog or drift. This design supports accurate pH determination in strong bases, saline process streams, and other high-ionic-strength media commonly encountered in chemical and industrial laboratories.
This article is part of pH electrodes & sensors, in pH & electrochemistry.
The electrode has a shaft length of 165 mm and is equipped with an S7 plug head; a connection cable is not included and can be selected according to the meter in use. Supplied as one piece from manufacturer WTW – a Xylem brand, the SenTix® H is intended for precision work where junction performance and alkaline durability are critical. Typical uses include monitoring of alkaline process baths, high-salt analytical samples, and research applications that require a robust liquid-junction electrode with a detachable S7 interface for flexible cabling.

Questions about SenTix® H, Precision pH combination electrode with ground diaphragm for high alk
What is this article?
SenTix® H, Precision pH combination electrode with ground diaphragm for high alk 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.
