1.General Introduction
Yokogawa SC8SG conductivity sensor is mainly used in applications such as liquid conductivity measurement for manufacturing processes and pure water resistivity measurement in the semiconductor, food, pharmaceutical, and power industries. A wide variety of mountings are available including screw-in type, flow-through type with screw joint, and flow-through type with flange which combine to work with conductivity analyzer converter FLXA21. FLXA202, FLXA402, SC450G.
