Industrial EC & TDS Sensor MODBUS-RTU (RS485) Brand_Pololu or use the wireless capabilitiesThe EC & TDS Sensor measures conductivity, salinity, and TDS with automatic temperature compensation. With IP68 protection, RS485 output, and low power use, its perfect for reliable water quality monitoring. The EC & TDS Sensor with hook up wires measures electrical conductivity (EC), salinity, and total dissolved solids (TDS) in liquids, making it ideal for monitoring water quality in a wide range of applications. Built to industry standards, the
