The FDO 70x IQ The FDO 70x IQ sensor is a dissolved oxygen measuring device that uses optical measurement technology, manufactured by WTW (a Xylem brand).
In Vietnam, with the rapid development of industrialization and urbanization, the demand for water quality monitoring is increasing. With its corrosion resistance and minimal calibration requirements, the FDO 70x IQ is an ideal choice for industries such as wastewater treatment, aquaculture, and environmental monitoring.
Dissolved Oxygen (DO) is an important parameter that directly affects the survival of aquatic organisms and the efficiency of water treatment processes.
Key Features of the FDO 70x IQ
The FDO 70x IQ sensor offers a range of superior features, making it stand out compared to competing products on the market:
- Minimal calibration The device is factory calibrated before shipping.
- Independent of flow rate Suitable for environments with unstable flow conditions, such as wastewater or fish farming ponds.
- Insensitive to air bubbles The 45° sensor membrane angle minimizes the impact of air bubbles.
- Corrosion-resistant All components in contact with water are made of titanium and plastic, optimized for seawater, river water, or environments with high salinity.
- Durable design: It can operate at pressures up to 10 bar, making it suitable for heavy industrial applications.
