Conductivity Sensor SC210G

Yokogawa has been supplying superior on-line analyzers for monitoring or controlling the conductivity of liquids or 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 SC210G conductivity sensor is widely used in various water and manufacturing process applications. A wide variety of mountings are available including screw-in type, flange type, flow-through type, and screw-in type with gate valve.
