Desun DS380 Optical Digital RS485 Online Dissolved Oxygen Sensor DO Sensor for Fish Pond

 
Fish and other aquatic animals require different levels of DO depending on their size, age, and species. Typically, the minimum DO level that fish require is 5 mg/L, while some species such as trout and salmon require 8-10 mg/L. Young fish and larvae require even higher DO levels due to their higher metabolic rates. Additionally, the dissolved oxygen level required for fish to thrive increases with increasing water temperature, as warmer water holds less dissolved oxygen than cooler water.
 

 
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.
