Do Meter Dissolved Oxygen Sensor Measurement Device Manufacturers

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-700 Dissolved Oxygen analyzer adopts 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.


n  Features 

u  Won't produce oxygen consumption when measuring and no requirement of flow rate and stirring.

u  Factory calibration, not need calibration for a year and can carry out field calibration.

u  Digital sensor, high anti-jamming capacity and far transmission distance.


n  Applications

DO online monitoring of different technological processes such as regulating reservoir, biochemical  pool and effluent of sewage  treatment plant.
