The multi - parameter water quality analyzer is a highly integrated water quality testing device that can precisely measure and analyze multiple key parameters of water bodies simultaneously. It integrates various advanced sensors, such as temperature sensors, dissolved oxygen sensors, Ph sensors, turbidity sensors, and ammonia nitrogen sensors, enabling a comprehensive and detailed understanding of various indicators of water bodies. The outer shell is made of high - strength, corrosion - resistant engineering plastics or metal materials with excellent protective properties, allowing it to adapt to various harsh water quality testing environments, including wild rivers, lakes, and industrial wastewater discharge outlets. Its advantages lie in its powerful functions, precise measurements, and simple operation. It can quickly obtain comprehensive information about water bodies, providing a scientific basis for water quality evaluation, pollution control, and water resource management. It is widely used by environmental protection departments for regular monitoring of water body environments to promptly detect water quality changes and pollution problems; in aquaculture, it enables real - time monitoring of various parameters of aquaculture water bodies, providing data support for aquaculture management; in industrial production, it monitors the water quality during the production process to ensure that the production water meets process requirements.
