Featured Applications
- Online monitoring of surface water quality in rivers, lakes, reservoirs, drinking water sources, etc., to grasp real-time changes in water quality and provide data support for water environment governance.
- 24/7 monitoring of aquaculture water bodies such as fish ponds, shrimp ponds, and nursery farms, precise control of key indicators such as dissolved oxygen and pH, and improvement of aquaculture survival rate and yield.
- Monitoring the water quality of industrial/domestic sewage discharge outlets and river discharge outlets, promptly detecting abnormal discharges, and assisting in environmental law enforcement and pollution tracing.
- Long term unmanned automatic monitoring of open water bodies such as agricultural irrigation water, landscape lakes, artificial wetlands, and urban rivers ensures water safety and water environment stability.

Daily maintenance and precautions
Installation specifications
- Placed in waters with a depth of ≥ 700mm, avoiding waterways and areas of strong disturbance.
- Use the standard anchor system to secure and prevent drifting collisions.
- Before installation, check that the sensors, cables, and solar panels are intact.
- Automatically collect data after power on, and the platform can be used by binding the device.
Calibration and Maintenance
- Make sure to clean the dirt off the floating bodies, sensors, and solar panels on a regular basis.
- In places with bad water quality, it is best to clean the sensor once a month and calibrate it every three to six months.
- Use a delicate cloth to clean the panel and don’t let anything hard scratch it. Sensors should not be hit hard.
- Take the sensor off and calibrate it with one or two points when the data drifts. Then put it back on.
