Dissolved oxygenis the most important parameter in the biochemical process of aquatic environment. It is also often used as a tracer in marine research. The optical dissolved oxygen sensor is a high-performance, low-power in-situ sensor for measuring the dissolved oxygen. It has so many advantages: small size, low power consumption, fast response,high stability, etc. It can provide long-term stable, accurate and reliable dissolved oxygen measurement data, which can be widely used in marine environmental investigation and monitoring.

The Deep-Sea pH Sensor is a mass-produced sensor specifically designed for deep-sea environments. Based on the response principle of solid-state oxides to pH, it utilizes micro-scale solid-state oxide pH electrode fabrication technology and weak electrode potential signal detection and processing technology to achieve highly stable and sensitive pH measurements. The sensor supports long-term, unattended in-situ monitoring and can be integrated into fixed platforms such as shore-based stations, shipboard equipment or buoys

The shallow water pH sensor is designed based on electrochemical principles, offering long-term stability and ease of maintenance. It enables reliable pH measurements in complex marine environments. The sensor can be used either independently or integrated into multi-parameter water quality monitoring systems. Ithas been applied in marine research, environmental monitoring, aquaculture.
