Toroidal (inductive) conductivity sensor that reliably measures conductivity in highly conductive electrolyte solutions up to 2 S/cm (2,000,000 µS/cm). The toroidal design — no metal electrodes touching the process — makes it the right choice for dirty and corrosive applications where contacting sensors (like the 400) foul or corrode. Best for chlor-alkali, salt brines, acid/caustic transfer, and waste streams. Mounting variants for in-pipe insertion, flow-through, and submersion.

Contact Us or Call (661) 327-8681Toroidal (inductive) conductivity sensor for highly conductive electrolyte solutions up to 2 S/cm. No-contact design ideal for corrosive, dirty, or high-conductivity liquids. Submersion or insertion installation. PEEK or Tefzel construction for chemical resistance.
Rosemount is configurator-heavy and quote-only — Valley Instrument verifies option compatibility, lead time, and pricing before confirming your order.
Toroidal conductivity sensor with robust, fouling-resistant geometry for harsh, corrosive, and fibrous liquid applications — pulp & paper, sugar processing, food/beverage CIP/SIP. Same 0-2 S/cm range as the 228 but with body materials and dimensions optimized for process applications with extreme fouling potential. The 226 outlasts the 228 in fibrous and abrasive media; the 228 wins in tighter pipes (smaller form factor).
Contacting (electrode) conductivity sensor for clean, low-conductivity liquids — high-purity water, ultrapure rinse water, clean cooling water, condensate. Factory-measured cell constant (0.01, 0.1, or 1.0/cm) ensures out-of-the-box accuracy with no initial calibration. Wetted parts: titanium electrodes, 316 SST body, PEEK insulator, EPDM O-rings. Direct screw-in 3/4 in MNPT process insertion. Range: <20,000 µS/cm. The right choice when sample is clean — toroidal sensors (228 / 226) are over-spec for ultrapure water.
