Product Description

Product Information

BGT CE Online RS485 4-20mA Optical Hydroponics Aquaculture Fluorescence DO Sensor Seawater Dissolved Oxygen Sensor

BGT-WDO(K2) integrated online fluorescence dissolved oxygen sensor is designed and fabricated based on the quenching principle of excited fluorescence by specific substances in physics. When the excitation light is shone on the fluorescent material on the surface of the fluorescent film head, the fluorescent material is excited and emits fluorescence. The quenching time of fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent film head.By detecting the phase difference between fluorescence and excitation light and comparing with the internal calibration curve, the concentration of oxygen molecules can be calculated, and the final value can be output after temperature and salinity compensation.
