Description
pH electrode for low conductivities and heavy contamination, S7 is a glass pH sensing electrode designed for demanding process and laboratory media where conductivity is low and fouling risk is high. It combines a PTFE diaphragm in a double junction arrangement with a pressure rating of 8 bar, supporting stable measurement even when samples tend to clog conventional junctions. The sensor uses a PG 13,5 screw connection for secure process mounting and straightforward exchange. Intended for low-conductivity streams and heavily contaminated samples, the glass body and PTFE double diaphragm help maintain reliable contact with the measuring medium under elevated pressure. Supplied as a single piece with a net weight of 0,1 kg (gross weight 1,1 kg), this electrode from manufacturer Hanna Instruments fits standard industrial pH installations that require an S7-style process electrode. Typical use cases include monitoring of low-ionic-strength waters, wastewater with high solids loading, and other harsh aqueous matrices where junction blocking must be minimised. The robust glass construction and double PTFE junction support continuous or intermittent pH control loops in plant and pilot environments.
This article belongs on pH electrodes & sensors, in pH & electrochemistry.

Questions about pH electrode for low conductivity and heavy contamination, S7
What is this article?
pH electrode for low conductivity and heavy contamination, S7 is the article on this page. Luminix Health distributes Hanna Instruments 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.
