DO3 by Eco Sensors (a division of KWJ Engineering) is a rapid, simple to use device for checking the ozone concentration in water and is calibrated in mg/L (same as parts-per-million by volume in water).  This small, battery-operated detector offers an inexpensive alternative to more costly inline monitors and requires no disposable reagents.  DO3 is a practical, versatile detector for applications where the user needs to confirm that a system is ozonating the water, but does not need the “accuracy” and high cost of complicated analytical, inline dissolved ozone meters.
