Yokogawa has been supplying superior on-line analyzers for monitoring or controlling the conductivity of liquid or solutions.
Now, Yokogawa provides the FLXA402 four-wire conductivity/resistivity converter, the FLXA202 and FLXA21 two-wire conductivity/resistivity transmitters. Yokogawa also provides many kinds of sensors for accurately measuring liquid conductivity when using converters/transmitters.
The combination of Yokogawa's converters/transmitter and sensors meets the demanding ultrapurewater requirements of the growing semiconductor and pharmacentical markets in addition to traditional water quality measurements for standard power plant and chemical applications.
The SC4AJ conductivity sensor has a convenient, compact design and is widely used in various applications including boiler water and hydroponics conductivity measurement and pure water resistivity measurement in the semiconductor, food, pharmaceutical, and power industries.
