PFDO-700
PROBEST
90268090
Measurement Principle
PFDO-700 Dissolved Oxygen Sensor 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.
Features
The sensor adopts new type of oxygen sensitive membrane, with NTC temperature compensated function, whose measurement result has good repeatability and stability.
Won't produce oxygen consumption when measuring and no requirement of flow rate and stirring.
Breakthrough fluorescence technology, without membrane and the electrolyte and almost not need maintenance.
Built-in self-diagnosis function to ensure the accuracy of data.Plug-and-play sensor, quick and easy installation.
Factory calibration, not need calibration for a year and can carry out field calibration.
Digital sensor, high anti-jamming capacity and far transmission distance.
Standard digital signal output, can achieve integration and networking with other equipment without controller.
Applications
DO online monitoring of different technological processes such as regulating reservoir, biochemical pool and effluent of sewage treatment plant.
DO online monitoring of water plant, surface water, industrial process water and aquaculture and etc.
