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.
