In addition to aeration, other factors can affect DO levels in aquaculture systems. For example, the presence of excess organic matter, such as uneaten feed or feces, can lead to oxygen depletion as bacteria consume the organic matter and consume DO. Therefore, it is important to manage feeding and waste management practices to ensure that excess organic matter does not accumulate in the system.
Dissolved Oxygen Sensor Brief Introduction
The DS380 series of fluorescent dissolved oxygen sensors use a new type of fluorescence lifetime technology and high-performance fluorescent materials. The fluorescent dissolved oxygen sensor is based on the quenching principle of the specific fluorescence of a specific substance in physics. Blue light from a light-emitting diode (LED) illuminates the fluorescent material on the inner surface of the fluorescent cap, and the fluorescent material on the inner surface is excited to emit red light by detecting the phase difference between red and blue light and the internal calibration value. The ratio is calculated to calculate the concentration of oxygen molecules, and the final value is automatically compensated by temperature and pressure.
