Description
SenTix® Sur is a surface pH electrode intended for pH measurement on smooth surfaces such as paper, film material and comparable substrates. Unlike conventional immersion electrodes, it is designed for direct contact readings where liquid immersion is impractical or impossible. The electrode features an S7 plug head and is supplied without a connecting cable, so it can be paired with suitable laboratory cables and meters according to the existing setup. From manufacturer WTW - a Xylem brand, this specialised sensor supports analytical and quality-control work in paper, packaging, materials and related laboratories. Its geometry enables stable surface contact on flat or gently curved non-porous samples. Supplied as a single piece with a net weight of 0,108 kg, the SenTix® Sur integrates readily into routine pH workflows that already use S7-compatible instrumentation. It is particularly useful when surface-specific pH data are required alongside standard bulk-solution measurements, extending the range of samples that can be characterised with a laboratory pH system.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about SenTix® Sur, Surface pH combination electrode for measurements on smooth surface
What is this article?
SenTix® Sur, Surface pH combination electrode for measurements on smooth surface 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.
