The EC & TDS Sensor measures the conductivity, salinity, and total dissolved solids (TDS) in a liquid. The output signal can be RS485 or Analog Voltage. Determining the conductivity, salinity, and TDS of a liquid has many important applications. The EC & TDS Sensor is widely used in monitoring water quality.
