Trolmaster Aqua-X Reservoir EC/Temp Sensor (PCT-1)

The TrolMaster PCT-1 Reservoir EC/Temperature Sensor allows growers to accurately monitor nutrient strength and water temperature directly inside their reservoir when using the Aqua-X irrigation control system. In hydroponics and automated indoor growing setups, maintaining the correct electrical conductivity (EC) and nutrient solution temperature is essential for stable nutrient uptake, healthy root development and consistent plant growth.

The PCT-1 continuously measures EC and reservoir temperature and sends this data to the Aqua-X controller for real-time monitoring and data logging. By tracking these conditions, growers can ensure their nutrient solution remains within the optimal range throughout vegetative growth and the flowering stage. This helps prevent nutrient imbalances that can lead to plant stress or reduced yield.

With a long probe cable for flexible installation, the sensor can be easily positioned inside reservoirs while the Aqua-X system monitors and records the readings.

Key Benefits

• Accurately measures nutrient EC levels in the reservoir
• Monitors nutrient solution temperature for stable root zone conditions
• Designed for use with the TrolMaster Aqua-X irrigation control system
• Helps optimise nutrient uptake and plant health
• Supports stable hydroponic system management
• Long sensor cable for flexible reservoir placement
• Enables data monitoring and logging through the Aqua-X controller

How It Solves Grow Problems

In hydroponic systems, nutrient concentration and reservoir temperature can change quickly as plants feed and environmental conditions fluctuate. If EC levels drift too high, plants may experience nutrient burn or salt buildup. If EC drops too low, plants may suffer from nutrient deficiencies that slow vegetative growth and reduce flowering performance.

The PCT-1 provides continuous monitoring of reservoir EC and temperature, allowing growers to quickly identify changes in nutrient strength and adjust their feeding programme accordingly.

Maintaining stable nutrient levels helps ensure consistent nutrient uptake, strong root development and healthy plant growth across hydroponic systems. This stability supports improved plant health, stronger flowering and higher yields.

How to Use

1. Connect the PCT-1 sensor probe to the TrolMaster AMP-2 sensor board.

2. Connect the AMP-2 board to the Aqua-X irrigation control system.

3. Place the EC/temperature probe directly into the nutrient reservoir.

4. Ensure the probe remains fully submerged in the solution for accurate readings.

5. Monitor EC and temperature readings through the Aqua-X controller or the TM+ mobile app.

6. Adjust nutrient strength or reservoir conditions as needed to maintain optimal growing parameters.
