In the field of water environment governance and water quality monitoring, accurately capturing the concentration and changes of various ions in water is a key link to ensure water quality safety and promote water ecological protection. As a core technical product for water quality monitoring, the Ion Selective Sensor has become the focus of the industry with its high-sensitivity detection capability for specific ions.

Ocean currents, the dynamic flows of seawater, are vital components of Earth's climate system, influencing weather patterns, ecosystems, and maritime safety. Precisely measuring the speed and direction of these invisible forces is crucial for scientific research, environmental monitoring, ocean engineering, and fisheries. But how do scientists and engineers accurately capture this data in the deep, high-pressure, saltwater environment? The answer lies in a sophisticated instrument: the Electromagnetic (EM) Current Meter​​.

​​The safety and health of our daily drinking water, rivers and lakes, and even swimming pools are closely tied to a crucial indicator—pH level. Today, let's uncover the mystery of the pH sensor, understanding this "invisible sentinel" guarding water quality safety.

On July 19th, as one of the supporting activities of the China - Shanghai Cooperation Organization Local Economic and Trade Cooperation Conference, the SCO International Exchange and Cooperation Conference on the Development of Marine Internet of Things Industry was grandly held at the Qingdao - SCO Pearl International Expo Center. With the theme of "Gathering SCO, Connecting the Ocean Intelligently", this conference aims to deepen international exchanges and industrial cooperation in the field of marine Internet of Things within the framework of the Shanghai Cooperation Organization, build an efficient docking platform among governments, enterprises, universities and research institutions, and promote the transformation of marine scientific and technological achievements and the coordinated development of the industrial chain.​

Blue - Green Algae Bloom in Ponds: Ecological Threats and Monitoring Needs

In the ecosystems of aquaculture ponds and landscape ponds, the massive proliferation of blue - green algae has become a frequent and tricky problem. In terms of causes, eutrophication is the core driver. Agricultural non - point source pollution (such as fertilizers flowing in with rainwater), aquaculture tailwater discharge (excessive feeding leading to nitrogen and phosphorus enrichment), and domestic sewage leakage continuously input nutrients like nitrogen and phosphorus into the water body. When the water temperature is in the range of 25 - 35℃ and the water body has poor fluidity (such as low frequency of pond water exchange and insufficient water power), blue -green algae will take advantage of these "nutrients" and suitable environments to enter a stage of explosive growth.

In today's era with increasingly stringent requirements for water quality, Oil In Water Sensor, as key devices for monitoring the content of oil substances in water, play an indispensable role in many fields such as environmental protection, industrial production, and water quality monitoring. A deep understanding of their working principles and operation techniques is of great significance for ensuring their efficient and accurate operation.​

In recirculating aquaculture systems (RAS), the stability and controllability of water quality are core elements to ensure the healthy growth of cultured organisms and improve aquaculture efficiency. Scientific and effective water quality monitoring relies on precise control of key parameters. The following details the key water quality parameters that need to be monitored in recirculating aquaculture systems.​

In the process of wastewater treatment, monitoring effluents is a key link to protect the ecological environment and public health. By monitoring specific parameters, we can timely grasp the effect of wastewater treatment and ensure that the quality of the discharged water meets relevant standards. The following are the key effluent parameters that should be monitored in wastewater treatment:

Dissolved oxygen in water plays a crucial role in the survival of aquatic organisms and the balance of the entire aquatic ecosystem. As two key indicators for measuring the state of dissolved oxygen in water, dissolved oxygen concentration and saturation are closely and complexly related. A deep understanding of this relationship is of great significance for water resource protection and water environment monitoring.​

Drinking water laboratory equipment is mainly used for testing the quality of drinking water. Tap water laboratory equipment can be divided according to the different types of water quality parameters tested, including microbial indicators, toxicological indicators, sensory properties and general chemical indicators, radioactivity indicators, disinfectant indicators and requirements.
