Online dissolved oxygen monitor for fish farm Water quality monitoring DO sensor

Dissolved oxygen (DO) is an essential component of aquatic ecosystems, including aquaculture systems. DO is crucial to the survival, growth, and reproduction of aquatic organisms. It is a limiting factor in the carrying capacity of a given system, and thus its concentration must be carefully monitored and controlled to ensure the health and productivity of the organisms being cultivated. The adequate dissolved oxygen level for aquaculture depends on several factors, including the species being cultivated, water temperature, salinity, and other environmental factors.



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.
