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 China in Line RS485 Industrial Dissolved Oxygen Water Sensor Manufacturer 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.
