The ECTDS10 measures the conductivity, salinity and total dissolved solids (TDS) in a liquid. The output signal can be RS485, Analog Voltage or Analog Current. Determining the conductivity, salinity and TDS of a liquid has many important applications. The ECTDS Sensors are widely used in monitoring soil conditions and water quality.

This ECTDS10 Sensor was designed with industry standards. It is designed with ATC (automatic temperature compensation), making sure the data is accurate regardless of the temperature changes. This ECTDS Sensor is IP65 rated, waterproof in a tight seal, capable of withstanding long-term constant use in professional application scenarios. It comes with a cover that is rated IP68.
