Maintain absolute control over your nutrient reservoir with the TrolMaster PCT-2, a commercially rated In tank EC and Temperature sensor. Engineered for high-demand cultivation environments, this heavy-duty probe provides continuous, high-precision monitoring of Electrical Conductivity (EC) and water temperature.
Unlike standard hobbyist probes, the PCT-2 is specifically designed for submerged tank use. It delivers the stable, reliable data required for automated fertigation systems, ensuring your nutrient solution stays within the optimal range for maximum crop performance.
Commercial Grade Precision
The PCT-2 is built to withstand the constant exposure of a nutrient reservoir while maintaining surgical accuracy. It acts as the "eyes" of your irrigation system, sending live data to your master controller so you can react to nutrient fluctuations before they affect your plants.
  • Dual-Parameter Monitoring: Tracks both nutrient concentration (EC) and solution temperature simultaneously.
  • Built for Tanks: The heavy-duty design is optimized for direct placement into water tanks and reservoirs.
  • Wide-Scale Utility: Beyond hydroponics, its robust build is suitable for aquariums and laboratory applications.
System Integration & Compatibility
The PCT-2 features a Mini DIN terminal for a secure, interference-free connection to your TrolMaster ecosystem via the AMP-2 or AMP-3 sensor boards.
  • Aqua-X Series: (NFS-1 via AMP-2; NFS-2/NFS-3 via AMP-3).
  • Tent-X (TCS-1): Via AMP-3.
  • Green-X (GCS-1): Via AMP-3.
Key Technical Specifications
  • Cable Length: 3.6-meter (11.8ft) heavy-duty cable for flexible placement in large reservoirs.
  • Operating Range: Temperature 32-122°F | Humidity <90%.
  • Connection Type: Mini DIN Terminal.
Pro Maintenance for Maximum Accuracy
  • Monthly Cleaning: Prevent "sensor drift" by removing biofilm. Soak the tip in a mild probe cleaner and gently brush the metal pins with a soft tool.
  • Signal Integrity: Keep the sensor cable away from high-voltage pump or LED power lines to prevent electrical "noise" from causing jumping readings.
  • Thermal Equilibrium: When first placing the probe in the tank, allow it to sit for 10 minutes to acclimate to the water temperature before trusting the first reading.
Master your nutrients. The TrolMaster PCT-2 is the durable, accurate solution for commercial growers who refuse to compromise on water quality monitoring.

Commercial-Grade EC & Temperature Monitoring for Precision Irrigation

The TrolMaster PCT-2 Heavy-Duty EC & Temperature Sensor delivers continuous, high-accuracy monitoring of your nutrient solution, helping growers maintain the ideal conditions for healthy root development and maximum nutrient uptake. Designed for demanding commercial environments, the PCT-2 measures both electrical conductivity (EC) and water temperature, giving you the real-time data needed to optimise irrigation, reduce nutrient waste and produce consistently healthier crops. It connects to compatible Aqua-X, Aqua-X Pro, Aqua-X Plus, Green-X and Tent-X systems via an AMP-2 or AMP-3 Sensor Board.

Built with a heavy-duty commercial probe and a 3.6-metre cable, the PCT-2 offers flexible installation in nutrient reservoirs and is suitable for hydroponics, commercial greenhouses and professional irrigation systems. By continuously monitoring EC and water temperature, growers can quickly identify changes in nutrient concentration before they impact plant health, helping to improve crop consistency and maximise yields.

Frequently Asked Questions

The PCT-2 continuously measures electrical conductivity (EC) and water temperature, helping growers monitor nutrient strength and irrigation conditions in real time.

The PCT-2 is a heavy-duty commercial-grade EC and temperature sensor designed for more demanding applications and long-term reliability, while the PCT-1 is the standard reservoir sensor.

The PCT-2 is compatible with:
Aqua-X (NFS-1)
Aqua-X Pro (NFS-2)
Aqua-X Plus (NFS-3)
Green-X (GCS-1)
Tent-X (TCS-1)
using the appropriate AMP-2 or AMP-3 Sensor Board.

Yes. The PCT-2 connects through an AMP-2 or AMP-3 Sensor Board, depending on your controller. It cannot be connected directly to the controller.

Maintaining the correct EC ensures plants receive the right nutrient concentration, while stable water temperatures support healthy root development, oxygen availability and efficient nutrient uptake. Together they help prevent nutrient deficiencies, overfeeding and unnecessary crop stress.

The PCT-2 is designed primarily for use in nutrient reservoirs but is also suitable for hydroponic systems, aquariums, laboratories and other water-monitoring applications.

The PCT-2 includes a 3.6-metre cable, allowing flexible installation within larger nutrient tanks and irrigation systems.

The PCT-2 is ideal for commercial growers, hydroponic farms, greenhouse operators and serious hobby growers who require reliable EC and temperature monitoring as part of a fully automated irrigation system.
