DO-700 Dissolved Oxygen analyzer adopts the fluorescence method to measure dissolved oxygen. The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated.

The probes are waterproof and can be submerged completely, which makes them ideally suited for e. g. environmental research applications, aquaculture, and measurement in sewage.
DO online monitoring of different technological processes such as regulating reservoir, biochemical pool, and effluent of the sewage treatment plant.
DO online monitoring of water plants, surface water, industrial process water and aquaculture and etc

Won't produce oxygen consumption when measuring and no requirement for flow rate and stirring.
Factory calibration does not need calibration for a year and can carry out field calibration.
Digital sensor, high anti-jamming capacity, and far transmission distance.
