Rosemount™ 225 Toroidal Conductivity Sensor
rosemount 225 toroidal conductivity sensor
The Rosemount 225 Toroidal Conductivity Sensor is intended for use in pharmaceutical and food & beverage applications where a sanitary design is required.
This conductivity sensor is corrosion and fouling resistant and is ideal for measuring the concentration of CIP solutions, detecting product/water interfaces, checking product quality, and monitoring eluents in chromatographic separations.
