Aquistar Conductivity Loggers: CT2X-Cableless

The Aquistar CT2X is a Conductivity and Temperature SmartSensor sensor with built-in data-logging for measuring conductivity and temperature in water. Add Pressure Measurement to the same probe and monitor two parameters with one small unit. The CT2X is used for wetland surveys, saltwater intrusion monitoring, agricultural runoff studies, discharge monitoring, and more.

The CT2X Cable-Less can be preconfigured for reading frequency and start and stop times then installed independant of electrical cables for autonomous operation or installed in an INW Multiparameter Adapter for real-time and remote data collection of multiple parameters on a single cable.

The CT2X comes with powerful, easy-to-use Aqua4Plus software, affording the user extensive control, including real-time monitoring, flexible programming, and versatile data display options. 


Whether its one sensor or hundreds use the CT2X with WaveData Remote data collection and access your data remotely.
