Portable Dissolved Ozone Detector "DO3"
Portable Dissolved Ozone Detector "DO3"DO3 by Eco Sensors is a fast, easy to use device for checking the ozone concentration in water and is calibrated in mg/L (same as parts-per-million by weight 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 the presence of ozone in water.
For checking residual dissolved ozone levels in bottled water, swimming pools, spas, water treatment systems, aquariums, food washing and canning, wineries, agriculture, cooling towers, research projects, and much more.
Equally useful in the plant, lab, or field.
Uses 200 ml samples. The sensor does not contact the water.
DO3 provides fast readings (5 minutes or less), with typical accuracy of ±25%. DO3 measures the ozone in the airspace above the sample, using Henry?s Law which describes the ratio between the ozone actually present in the water and the ozone in the air immediately above the surface of the water. While affected to some extent by temperature and atmospheric pressure, this measurement is sufficiently accurate for use in a wide range of ozonated water applications and compares well to more costly analytical instruments and the inconvenient colorimetric determinations.
- User replaceable battery; portable power for months of detection
- Stores up to 10 readings for remote sampling
- Simple and repeatable bottle sampling method
- No fouling of sensor, no special probes
- Digital display
- No consumables, no chemistries, no colour matching
