Rosemount™ 226 Toroidal Conductivity Sensor
rosemount 226 toroidal conductivity sensor
The Rosemount 226 toroidal conductivity sensor measures conductivity in highly conductive liquids up to 2 S/cm (2,000,000 ?S/cm).
This toroidal/inductive sensor has a robust fouling-resistant design which makes it ideal for measuring conductivity in harsh, corrosive and fibrous liquid applications.
