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.

The testing method standards in our country include: "Determination of dissolved oxygen in water - Iodometric method" (GB7489-1987), "Determination of dissolved oxygen in water - Electrochemical probe method" (HJ506-2009), and American ASTM standard (D888-05). The first two are national and industry standard methods in China, and the latter is a standard method recognized by the US Environmental Protection Agency.

In the global field of marine ecological monitoring and water environment management, biofouling-induced sensor failure has become a recognized technical bottleneck. Qingdao LUMINSENS Marine Technology Co., Ltd. has successfully developed a dissolved oxygen (DO) fluorescence sensor with revolutionary antibacterial performance through industry-university-research integration, surpassing international counterparts in core technical indicators and providing full-cycle reliable monitoring solutions for marine ranching, wastewater treatment, ecological research, and other scenarios.

From June 13 to 15, 2025, Qingdao LUMINSENS Marine Technology Co., Ltd. showcased its full range of water quality monitoring solutions at the 2025 Fuzhou International Fisheries Expo held at Fuzhou Strait International Convention and Exhibition Center. As a scientific and technological achievement transformation enterprise in the field of marine instrumentation, LUMINSENS took the theme of "Empowering Smart Aquaculture with Fluorescent Sensing Technology", presenting core products such as dissolved oxygen sensors, pH sensors, COD sensors, and system solutions like buoy water quality monitoring stations and portable multi-parameter analyzers, attracting extensive attention from industry clients, research institutions, and media.
