Online RS485 4-20mA Fluorescence Water Dissolved Oxygen Sensor for
River Water Quality Monitoring
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.
