Fluorescence Dissolved Oxygen Meter
A fluorometric dissolved oxygen meter is an instrument used for measuring the dissolved oxygen concentration in water bodies. It measures the phase difference between the excitation red light and the reference light, and compares it with the internal calibration value to calculate the concentration of oxygen molecules. This device replaces the traditional membrane-type electrodes with the fluorometric method, eliminating the need to replace the membrane and electrolyte, thereby reducing the maintenance workload. It does not consume oxygen, does not require flow rate and stirring, and is not affected by substances such as sulfides, thus improving the working reliability. It is particularly suitable for the harsh working conditions in the field of wastewater treatment.
The optical portable dissolved oxygen meter adopts the internationally leading fluorescence technology. The significant advantage of this fluorescence method for measuring dissolved oxygen is that it does not consume oxygen, does not require polarization, does not need frequent calibration, and is not interfered by H2S, heavy metals, grease, acids and alkalis. The portable DO instrument has the function of manual input for compensation of temperature, pressure and salinity. The instrument is equipped with an operation keyboard and a backlit display screen. The interface is simple, the functions are comprehensive, and the operation is convenient. This instrument can conveniently realize functions such as data measurement, data storage, parameter setting, and sensor calibration.

Application
Dissolved Oxygen Meter is an instrument used to measure the concentration of dissolved oxygen in a body of water, which is widely used in many fields. In aquaculture, dissolved oxygen meters are used to monitor the oxygen content of water bodies to ensure the healthy growth of fish and other aquatic organisms. In environmental monitoring, dissolved oxygen meters are used to assess the degree of pollution and ecological health of water bodies, and help formulate environmental protection measures. In wastewater treatment plants, dissolved oxygen meters are used to monitor oxygen levels during the treatment process and optimise treatment efficiency. In addition, dissolved oxygen meters are also used in laboratory research to help scientists understand the dynamics of oxygen in water bodies and its impact on ecosystems. In short, dissolved oxygen meters play an important role in aquaculture, environmental monitoring, wastewater treatment and scientific research.
