Conductivity Salinity TDS is widely use in industrial applications that involve the detection of contaminants in water. Salinity measurements when dealing with highly concentrated media such as seawater are also regularly monitored and provide important data for climate change science. Desalination plants are featuring more prominently throughout developing counties to supplement municipal water supplies. Their operating efficiency is a key factor to their viability and rely on accurate salinity measurements to monitor membrane performance. Envirosensors Pty Ltd has a full range of conductivity probes, meters and transmitters from WTW, Sensorex, Jenco Instruments & EDT Ion Direct.
