228 Toroidal Conductivity Sensor

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.
