Water content sensor (WCS-1) - TrolMaster

The WCS-1 sensor allows the user to monitor the water content within the growing medium. The humidity level is shown in real time on the sensor display. In the Aqua-X and in the APP you can see a graph with the history, visualize the drying of the substrate and thus be able to adjust the frequency of irrigation.

The WCS-1 probe can be used in numerous culture media. Before first use it is recommended to calibrate the probe in the specific substrate to be worked with along with the nutrient solution.

  1. Insert the WCS-1 probe into the substrate to be worked approximately 1/3 of the distance from the bottom of the container.
  2. Completely saturate the substrate to be worked with solution until runoff appears. DO NOT USE low EC water as this will affect calibration.
  3. Let the sample stand for 2-3 minutes.
  4. Press and hold the black button on the WCS-1 for 5 seconds. The 100% calibration will be displayed. Press the button again to confirm the 100% calibration.
  5. Once the 100% calibration is complete, REMOVE the WCS-1 probe from the substrate and quickly press the black button 5 times to initiate the 0% calibration. Press the black button again to confirm the calibration.

The meter will now be calibrated for the substrate you are working with, it is recommended to recalibrate the probe if the substrate type is changed and when starting a new growing cycle.
