Product Overview
Description
RDO-106 Online Fluorescence Dissolved Oxygen Sensor
RDO-106 integrated on-line 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.
1、No electrolyte is required and will not be polarized.
2、No oxygen consumption, not affected by flow rate.
3、Built-in temperature sensor, automatic temperature compensation.
4、Built-in salinity compensation, flexible parameter setting
5、Free from interference by chemicals such as sulfides
6、Small drift, rapid reaction, more accurate measurement.
7、Long service cycle, lower cost of use.
8、Simple replacement of fluorescent cap.
9、Rs-485 interface, Modbus/RTU protocol.
10、Low power consumption，anti-interference.
