What is a water quality sensor?
Water quality sensors measure water parameters such as conductivity, dissolved oxygen, pH, COD, residual chlorine, turbidity and so on through a variety of methods such as chemical, physical and biological reactions of water, providing data support for researchers, observers and engineers. It is used in laboratory research, environmental management improvement, Marine water quality assessment, hydraulic model calibration, sewage treatment and other fields. Water quality sensor is the measurement of PH, residual chlorine, turbidity, suspended matter, COD, BOD, conductivity, dissolved oxygen of a variety of sensors. Water quality does not refer to a specific day parameter, it contains several elements to measure the quality of water.
Type of water quality sensor
Water quality is a general concept that covers a wide range. Therefore, the construction of a complete water quality monitoring system is a complex project. The good news is that with the JXCT Water quality sensor and a water quality monitoring host, you can easily build your water Quality monitoring system.

The dissolved oxygen meter is a sensing device used to measure the amount of oxygen dissolved in water. The continuous measurement of dissolved oxygen concentration in water plays an important role in the field of water treatment. It uses the principle of fluorescence measurement. The fluorescent dissolved oxygen sensor is based on the quenching principle of active fluorescence by specific substances in physics. It does not consume oxygen and does not need electrolyte. There are two kinds: sea water and fresh water.

The chlorophyll (blue-green algae) water quality analyzer uses the characteristic that chlorophyll (blue-green algae) has absorption peaks and emission peaks in the spectrum, and emits monochromatic light in the spectrum absorption peak of chlorophyll (blue-green algae) to irradiate the water , The chlorophyll (blue-green algae) in the water absorbs the energy of monochromatic light, and releases a monochromatic light with another wavelength emission peak. The light intensity emitted by chlorophyll (blue-green algae) is proportional to the content of chlorophyll (blue-green algae) in the water. Proportional.
