Product Description

WQ-FDO Optical Dissolved Oxygen Sensor Description
The WQ-FDO Optical Dissolved Oxygen Transmitter is an instrument designed for measuring dissolved oxygen concentrations in liquids.  The WQ-FDO Optical Dissolved Oxygen Transmitters were developed to meet different requirements ranging from surface water monitoring programs to harsh waste water applications.  The optical dissolved oxygen transmitter has been specifically designed to meet the demanding requirements of the environmental monitoring and scientific research sectors, providing long term, accurate and reliable dissolved oxygen measurement.  The WQ-FDO Optical Dissolved Oxygen Transmitter has extremely low power requirements and a 4-20 mA output making it ideal for incorporation into remote environmental monitoring installations.

WQ-FDO Optical Dissolved Oxygen Sensor Features
• Extremely fast and precise optical DO sensor - outstanding for field and lab applications
• Proven green light technology for long operation life of sensor
• Beveled membrane repells interference that can be caused by air bubbles
• Universal protective armoring available
• Low power consumption and low maintenance
• Simple to integrate and operate
• One year sensor life

WQ-FDO Optical Dissolved Oxygen Sensor Applications
Long and short term monitoring for streams, rivers, lakes, aquaculture, thermocline profiling, industrial outfalls, wastewater, scientific research, homeland security, the food and wine industry, and more.
