The WCS-2 is part of the next generation of substrate monitoring for temperature, EC, and water content. 

TrolMaster’s WCS-2 Water Content Sensor is specifically designed to measure the water content data (percentage), temperature, and the EC of the grow media in the Aqua-X, Aqua-x Pro, and Hydro-X Pro Control System. 

Each WCS-2 sensor includes a five-prong sensor assembly connected to a LCD communication module (Display Screen & Button). To use the WCS-2, the five prong sensor is inserted into the grow media such as soil or rock wool to be measured. Normally placed horizontally about ⅓ of the way up from the bottom of the grow media container or rockwool block.  You can connect multiple Water Content Sensors (up to 50 WCS-2 on the NFS-2 and HCS-2 controllers, 8 on the NFS-1 controller). The NFS-2 screen will display the value of the 3 parameters (grow medium temperature, moisture level and EC) of each individual sensor.   

When using TrolMaster’s free TM+ app, you can see the water content %, temperature, and EC of the grow media on your Smartphone. You can view historical data graphs on the app and also receive notifications if the WCS-2 readings exceeds your highest or lowest alarm settings.

* The WCS-2 can only be used with the Aqua-X / Aqua-X Pro and the Hydro-X Pro
