Online 3 in 1 pH Dissolved Oxygen Temperature Sensor RS485 Modbus with Float System for Aquaculture Wastewater Monitoring
Product Vedio
Product Features
1. A sensor that simultaneously measures dissolved oxygen, dissolved oxygen saturation, pH, and temperature in water; suitable for both seawater and freshwater.
2. Employs fluorescence measurement technology, ensuring stability, reliability, long service life, and immunity to water quality and ion interference; typically requires no calibration.
3. Offers salinity compensation, pressure compensation, and temperature compensation; pH accuracy is 0.1%.
4. All-plastic housing(POM) with threaded mounting.
5. Special filter to prevent fish and shrimp from accidentally ingesting the substance. 6. Includes a matching float system.
Product Applications
Widely used in food, pharmaceutical, laboratory, aquaculture, and environmental monitoring fields; suitable for both seawater and freshwater.
