Product Description

The Rosemount 228 Toroidal Conductivity Sensor reliably measures conductivity in highly conductive electrolyte solutions up to 2 S/cm (2,000,000 µS/cm). These conductivity sensors work in dirty and corrosive applications where metal electrode sensors would otherwise fail. A robust sensor design makes the Rosemount 228 conductivity sensor ideal for measuring concentrations of acid, base and salt solutions.
