Factory Price online Optical or Polarographic do sensor electrode Dissolved Oxygen probe for aquaculture

 
In aquaculture systems, DO levels can fluctuate due to a variety of factors, such as the rate of oxygen consumption by the organisms, temperature, water flow rates, and the presence of dissolved organic matter. Therefore, it is important to monitor and maintain appropriate DO levels to ensure the health and productivity of the aquatic organisms being cultivated.
 

 
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.
