Conductivity Sensor SC8SG

Yokogawa supplies superior on-line analyzers for monitoring and controlling the conductivity of liquids and solutions.

Now, Yokogawa provides the SC450G four-wire conductivity/resistivity converter, the SC202G and SC202S two-wire conductivity/resistivity transmitters, and the SC100 panel mount conductivity converter. Yokogawa also provides many kinds of sensors for accurately measuring liquid conductivity when using converters/transmitters.

The combination of Yokogawa's converters/transmitters and sensors meets the demanding ultrapurewater requirements of the growing semiconductor and pharmacentical markets in addition to the traditional water quality measurement requirements of standard power plant and chemical applications.

The SC8SG conductivity sensor is widely 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.
