Remond RS485 Optical DO Probe Fluorescence DO Sensor/ Digital Dissolved Oxygen Probe Fish Culture

Product Description

The fluorescence method dissolved oxygen sensor is based on the fluorescence quenching principle. Blue light illuminates the fluorescent material to excite and emit red light. Since oxygen molecules can take away energy (quenching effect), the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules. By measuring the phase difference between the excitation red light and the reference light and comparing it with the internal calibration value, the concentration of oxygen molecules can be calculated.
