RS485 Online Multi-parameter Water Quality Sensor probe pH,conductivity/salinity/TDS/turbidity/DO/drinking water
Digital sensor, RS485 output, support MODBUS
All calibration parameters are stored in the sensor, and each probe is equipped with a waterproof connector, which can be easily replaced.
Equipped with an automatic cleaning device, it can effectively remove the dirt on the sensor surface, prevent the growth of microorganisms, and be more accurate and less maintenance.
Optional fluorescent dissolved oxygen, four-electrode conductivity, turbidity, digital pH, blue-green algae, and chlorophyll sensors are suitable for long-term online monitoring.
Integrated design, can connect 11 probes at the same time, measure 7 parameters.
