ESMDOA-1000 fluorescent dissolved oxygen meter Analyzer

ESMDOA-1000 fluorescent dissolved oxygen meter is based on the principle in physics that certain substances can quench active fluorescence. When modulated green light is shone onto the fluorescent material, it is excited and emits red light. Because oxygen molecules can take away energy (quenching effect), the time and intensity of the emitted red light are inversely proportional to the concentration of oxygen molecules. We use a red light source synchronized with the green light as a reference, measure the phase difference between the excited red light and the reference light, and compare it with internal calibration values to calculate the concentration of oxygen molecules, which is then temperature-compensated to output the final value.
