The Rosemount 222 Toroidal Flow Through Conductivity Sensor measures conductivity in highly conductive liquids up to 2 S/cm (2,000,000 μS/cm). The minimum conductivity is about 500 μS/cm. A noninvasive flow through design allows for in-line installations without any obstruction to sample and makes this conductivity sensor ideal for use in viscous or fibrous liquids.
