3000m Deep-sea Fluorescent Dissolved Oxygen Sensor Successfully Helps Zhejiang University Deep-sea Scientific Research
In the process of deep-sea environmental monitoring, marine ecology and carbon cycle research, the deep-sea scientific research group of Zhejiang University needs to carry out high-precision, long-term and stable in-situ monitoring of dissolved oxygen at a water depth of 3000 meters.
The scientific research mission relies on the underwater vehicle (ROV) to carry the detection equipment, which puts forward extremely high requirements for the pressure resistance, measurement accuracy, low temperature stability and data continuity of the sensor.
With its mature deep-sea sensor research and development and engineering capabilities, Qingdao Luminsens Marine Science and Technology has provided the research group with customized deep-sea fluorescent dissolved Oxygen Sensors and successfully completed the data collection task of deep-sea scientific research.


2. Products and Implementation Plan
2.1. Core products: 3000 m deep-sea fluorescent dissolved oxygen sensor
- Optical fluorescence measurement technology, no film, no electrolyte, not easy to drift, low maintenance
- Titanium alloy pressure structure, can work stably in the environment of 3000 meters deep sea
- Adapt to the underwater robot interface for real-time data acquisition and transmission
- Anti-biological attachment design, suitable for long-term underwater in-situ observation
The sensor is mounted on the underwater robot of the research group of Zhejiang University. It has completed multiple diving operations in the deep-sea environment and successfully obtained continuous dissolved oxygen profile data from the surface to the depth of nearly 3000 meters.


The above figure shows the profile data of key environmental parameters such as dissolved oxygen, temperature and salinity in the deep sea obtained in this scientific research. The curve is complete and the signal is stable, which truly reflects the environmental characteristics of deep sea water.
2.3. Technical Service Support
- Pre-docking: complete sensor adaptation according to ROV structure and communication protocol
- Medium-term guarantee: equipment commissioning, parameter configuration, on-site technical guidance
- Post-support: data analysis, quality control and research data optimization
