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.
