Introduction of the application of dissolved oxygen sensor

The optical dissolved oxygen sensor is more and more favored by various industries because it does not need electrode liquid, does not consume oxygen, and has the characteristics of plug and play. So in which applications do you need a dissolved oxygen sensor? The following Drifino company will introduce to you the application of dissolved oxygen sensors.

1. Aquaculture:
Aquaculture has freshwater (currently factory farming) and offshore mariculture methods. Dissolved oxygen in aquaculture is a parameter that must be measured. When the dissolved oxygen concentration in the water is lower than (3~4) mg/L, the fish will have difficulty breathing; if it continues to decrease, it will suffocate and die. At this time, the aerator needs to be turned on. When measuring dissolved oxygen in mariculture, salinity compensation is required to ensure the accuracy of the measurement. In instruments without automatic salinity compensation, hydrometers are generally used to measure the salinity of seawater, which requires manual data input for measurement. For seawater farming, we have dissolved oxygen sensors with titanium alloy shells, which are resistant to seawater corrosion. And it comes with pressure, salinity and temperature compensation. We also have matching salinity sensors.

2. Sewage plant and water plant
In order to ensure the quality of water value, the waterworks conduct dissolved oxygen detection on the water entering the waterworks. The sewage treatment plant also conducts dissolved oxygen measurement on the sewage entering the plant for treatment. In the sewage treatment plant, in order to ensure the normal life of microorganisms/bacteria in the water body and ensure the effect of water treatment, the dissolved oxygen content of the sewage pool must be controlled within a certain range. Daruifuno's matching dissolved oxygen controller can be used with a fluorescent dissolved oxygen sensor. The controller has 2 relays, which can be connected to aerators and other equipment for aeration and to adjust the dissolved oxygen content.

3. Surface water monitoring
Dissolved oxygen in rivers, rivers, lakes and seawater is one of the important indicators to measure water quality. This is a parameter that must be determined. The amount of dissolved oxygen in water reflects the quality of water. The reduction of dissolved oxygen in water is the main reason for the odor of water. We have developed a multi-parameter controller, which can be connected with pH, turbidity, conductivity and dissolved oxygen sensors to monitor routine parameters.

The above is the introduction of the application of dissolved oxygen sensor, Our company focuses on the R&D, production and sales of water quality analysis instruments. Our main products include online pH ORP analyzer, conductivity analyzer, turbidity analyzer, dissolved oxygen analyzer, COD analyzer, ammonia analyzer, etc. If you need water treatment related products, please contact us.
