Dissolved oxygen analysis of imported sewage

 
 
WDM dissolved oxygen online monitor, imported sewage dissolved oxygen analyzer
 
Principle: dissolved oxygen by fluorescence method
 
Interference factor: it has strong anti-interference ability and is basically not easy to be affected by other interference substances
Condition limitation: it will not consume dissolved oxygen in water, and there is no requirement for small flow rate of measuring medium
Stability and reliability: the fluorescent cap can still maintain its accuracy in case of scraping or partial pollution, and it is easy to clean
Maintenance amount: the maintenance amount is low
There is no need to calibrate and replace the electrolyte and film head, but only replace the fluorescent cap

It is widely used in dissolved oxygen monitoring in sewage plants, waterworks, water stations, surface water, aquaculture, industry and other fields

 
Do on-line monitoring of various process processes such as regulating tank, biochemical tank and effluent of sewage treatment plant;
 
Dissolved oxygen online sensor
The dissolved oxygen sensor measures dissolved oxygen by fluorescence method
The blue light emitted irradiates on the fluorescent layer, and the fluorescent material is excited to emit red light, and the oxygen concentration is inversely proportional to the time when the fluorescent material returns to the ground state
Using this method to measure dissolved oxygen, there is no oxygen consumption during measurement, the data is stable, the performance is reliable, there is no interference, and the installation and correction are simple

 
Breakthrough fluorescence technology with strong anti-interference ability
Without membrane and electrolyte, maintenance is basically unnecessary
Measurement does not consume oxygen and there is no flow rate / agitation requirement
 
Automatic air calibration
Place the sensor in the air and allow the instrument data to stabilize before starting calibration, while avoiding direct sunlight
Ensure that the settings of the sensor are correct
