    The Aquistar DO2 SmartSensor is the next generation in trouble-free oxygen sensing design for monitoring dissolved oxygen levels in water. The sensor uses fluorescence to detect and precisely measure oxygen concentration in the fluid surrounding the sensor. This method does not consume oxygen near the sensor as do membrane-type sensors, so the sensor maintains its calibration longer between service interruptions. DO2 contains an integrated data logger incorporated into the watertight probe housing.

    The DO2 sensor utilizes Aqua4Plus software providing easy to obtain, convenient, high-quality data for such applications as; dam discharge monitoring, aquaculture, landfill leachate monitoring, long-term surface water, remediation performance monitoring and municipal and industrial water treatment facilities.

    DO2 sensors can be used independently or networked locally, or remotely with the VZCOM system for data access anywhere in the world.

    Contact EON for assistance with configuration and accessories.
