Description
SenTix® 91 is a precision pH electrode with liquid electrolyte and an integrated temperature sensor. Featuring a spherical membrane, DIN connector and banana plug, the electrode measures 170 mm in length and comes with a 1 m DIN cable for straightforward connection to compatible meters. This configuration supports accurate pH determination with simultaneous temperature measurement, enabling automatic temperature compensation in laboratory workflows. Manufactured by WTW - a Xylem brand, the SenTix® 91 is intended for routine and precision pH analysis in research, quality control and analytical laboratories. The liquid electrolyte design promotes stable junction potential and reliable response across a range of aqueous samples. Its dual-connector arrangement (DIN plus banana) ensures broad instrument compatibility. The compact form factor and fixed cable length facilitate easy handling at the laboratory bench. Packaged as one piece, the electrode is ready for integration into existing pH measurement setups where temperature-compensated readings are required.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about SenTix® 91, Precision pH combination electrode, liquid electrolyte, built-in tem
What is this article?
SenTix® 91, Precision pH combination electrode, liquid electrolyte, built-in tem 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.
