SZ505-AWater Monitoring
Optical Dissolved Oxygen Sensor for Aquaculture
Measures dissolved oxygen from 0 to 20 mg/L or 0 to 200% saturation with ±3% accuracy, plus temperature from 0 to 50°C with ±0.5°C accuracy, and outputs via RS-485 MODBUS. This optical fluorescence sensor requires no membrane or electrolyte and is designed for continuous monitoring in aquaculture. Typical applications include fish ponds, shrimp farming, and other aquaculture water quality monitoring systems.
