Description
SenTix® 57 is a plastic pH electrode with liquid electrolyte and an integrated temperature sensor intended for high-performance laboratory pH measurement. The sensor includes an NTC 10 kOhm temperature probe, a BNC plug and a 2,5 mm jack plug on a 1 m cable, tailored for use with Sartorius instruments. Liquid electrolyte provides excellent junction performance and fast response, while the plastic body ensures mechanical robustness in daily laboratory handling. With a net weight of 0,1701 kg and a shortest blade length of 9 mm, the electrode remains convenient to manoeuvre in typical sample vessels. Produced by WTW - a Xylem brand and supplied as one piece, the SenTix® 57 is well suited to quality-control, research and process laboratories that demand temperature-compensated pH data together with the refillable characteristics of a liquid-electrolyte system. The combination of dual connectors, fixed cable and liquid fill supports accurate, reproducible measurements across a broad range of aqueous samples and analytical protocols.

Questions about SenTix® 57, Plastic pH electrode with liquid electrolyte, integrated temperature
What is this article?
SenTix® 57, Plastic pH electrode with liquid electrolyte, integrated temperature 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.
