Meet the CT Station
Obscape’s CT Station is the ideal all-in-one solution for real-time conductivity, temperature and salinity measurements. It combines the robust Obscape Power & Telemetry Module with a low-maintenance toroidal CT probe. Together they form a CT Station that is unchallenged in its ease of use. Whether you are monitoring aquatic habitats, estuarine hydrodynamics or salt intrusion, the Obscape CT Station will suit your needs.
Where oceanic and inland waters meet, the interaction of fresh and saline water create an intriguingly complex environment. A salt wedge intruding into an estuary or harbour basin can start dominating the hydrodynamics and may have a significant impact on sediment transport. Diverse and unique habitats can form through the interplay of salinity, tides and waves. Observations of conductivity, water temperature and salinity form the starting point for getting insight into these natural dynamics.

The CT Station is completely wireless. Power is supplied through built-in solar panels, while data are transmitted in real-time using a 4G GSM connection. Therefore, the CT Station is easy to install at any desired location within GSM coverage. There is no need to worry about access to mains power or third-party internet access points. Its wireless nature makes the CT Station very suitable for monitoring of remote areas.
While traditional CT probes suffer from rapid bio-fouling, compromising their accuracy and maintenance interval, the toroidal CT probe of Obscape’s CT Station was specifically designed to minimise marine growth. Paired with our powerful and robust workhorse, the Power & Telemetry Module, conductivity data make their way to your desktop in real-time.
