WTW Announces Optical Sensor Technology For On-line Dissolved Oxygen Measurement

WTW, a Nova Analytics company and leader in water quality measurement products, offers the FDO 700 IQ optical sensor for superior on-line dissolved oxygen measurement. Combining state-of-the-art optical technology with application applied benefits, the FDO 700 IQ is ideal for water and wastewater treatment and water pollution control.
Ensure efficient plant operation with reliable, accurate results and low cost of ownership using the next generation FDO 700 IQ sensor technology. Factory calibration and long term electrode stability (up to 18 months durability), eliminates the need for manual calibration. The membrane geometry has been optimized to prevent the accumulation of air bubbles on the membrane surface which can skew measurement results. The sensor therefore makes full practical use of the fundamental advantages of the optical D.O. measurement.
Optical D.O. measurement based on dye luminescence is strongly recommended and highly preferred for superior performance compared to conventional electrochemical sensors.
- No incident flow needed
- No calibration needed
- H2S insensitive
- High accuracy right from the start
- Maximum stability over extended time
- Minimum maintenance required
- Low cost of ownership
Innovative technology advancements over previous offering include:
- Intelligent Membrane with IQMC technology - Factory installed calibration guarantees calibration accuracy for up to 18 months
- Soft Green Light technology - Gentle light, not harsh UV light, is emitted to ensure long term stability by preventing the bleaching of the dye coating
- C2 calibrated optics - The sensor is precisely calibrated against the speed of light
- EPRS reference procedure - The reference path and the optical components are identically designed. The optical components are compensated by the reference path and in the measurement path allowing continuous high performance.
