Yosemitech Four-electrode Conductivity (salinity) Sensor provides more accurate, stable measurement and wider measurement range than traditional two electrode design. It has no polarization effect and can deploy in long periods of time without frequent maintenance. It supports RS485 MODBUS protocols. Y521-A Water Conductivity Sensor is widely used in surface water, municipal sewage, industrial wastewater, sewage treatment, industrial processes and aquaculture industries.

-RS-485 output , Modbus protocol compatible.
-Synchronous output of conductivity, salinity, TDS, temperature and other parameters.
-Built-in temperature sensor, automatic temperature compensation.
-Corrosion-resistant housing, waterproof grade IP68, can work underwater for a long time.
-Wide range and excellent interference rejection.
