Product Description

4-20ma Rs485 Fluorescence DO Dissolved Oxygen Probe Sensor for Water Quality

RK500-04 Dissolved Oxygen (D0)Sensor is based on the principle of quenching excited fluorescence byspecific substances in physics. When the excited light is irradiated on the fluorescent substance on thesurface of the fluorescent film head, the fluorescent substance is excited and emits fluorescence. Thefluorescence extinction time is affected by the concentration of oxygen molecules on the surface of thefluorescent film head.So the oxygen molecule concentration can be calculated by detecting thefluorescence extinction time.By using green light and unique phase technology, the membrane lifespanattenuation is reduced, and it can be used for more than 2 years without the need for calibration.D0 sensor can be widely used in chemical fertilizer, metallurgy,environmental protection water treatmentengineering,pharmaceutical, biochemical, food, aquaculture and water such as continuous monitoring ofdissolved oxygen in the solution.
